- 071 - Free Energy and the Equilibrium Constant
In this video Paul Andersen explains how thermodynamic and equilibrium reasoning can be related through changes in free energy and the equilibrium constant. When the delta G is negative the reaction shifts to the right or favors products. When the delta G is positive the reaction shifts to the left or favors reactants. In biological systems exergonic reactions (like cellular respiration) can be linked to endergonic reactions (like the production of ATP).

I know it's strange to say but I'm kind of sad that the series ended. Learning is much easier and more fun with Mr. Andersen. I hope he makes more Chemistry videos!
I just wanted to say how thankful I am for these video lectures. I was not feeling prepared for the AP Exam, so I watched all of the videos and took notes, and I was able to not only understand each of the concepts but also be able to learn how to tie all of the concepts together so that it makes sense how one thing leads to the next and the relationship between both. I really wish there could be some way for me to express my sincere thanks to you Mr. Anderson... I would not be able to have gotten to this point without your materials. I will continue to watch your videos as I take AP Bio and other science courses from here on out. Thank you SO SO much and I hope to see you again soon. Finishing this series makes it feel like my favorite show's season ended... but there are a lot more season comings that I am so exited for! Thank you; you are THE BEST educational UA-camr on this channel.
Good luck in your AP tomorrow guys..
Watched all 71 videos in less than 24 hours.
did your brain explode?
TheSick83 It sure felt like it.
Ammar Khan I got a 4 because of this, and I started studying 1 day before the exam. Not recommended. Bozeman saved me from a 2
sweet. What ever works i guess
My friend, I am currently struggling with ap biology and I must ask, you truly went from a two to a 4 just by watching bozeman's videos? Amazing
My AP Chemistry final is tomorrow, and my class never went fully in depth with relating Gibbs and equilibrium constant. As Equilibrium and Thermochem are the two biggest parts of the AP Chemistry exam, This video helped me put almost everything together, and helped answer almost all my questions for this year. Thank you SO much Mr. Anderson!
I've learned this a few times before in high school chemistry, and college gen chem. Now I am in med school and we covered this as part of the intro into metabolism and the professor confused me more than I ever have before lol. Watched this and makes much better sense now. Thanks.
+Jonathan Colin-Rizo I know! When he showed the delta G equation being on the opposite side of the equilibrium constant, It finally made so much intuitive sense!
+Jonathan Colin-Rizo Yep Mr. Anderson makes great videos that clarify science topics. Glad to see a med student using his videos.
you found the perfect path to teaching! no jokes that get you out of focus, no unnecessary editing with bright lights, we see you talking and we can follow through. Thank you sir, this is thank you in Arabic: شكرا
Watching this four years on and it's still SO beneficial. What a gift you have. Thank you.
Thank you so much Mr. Andersen! I never comment on UA-cam, but I want to truly thank you for all of your chemistry lessons. I watched every video in this series and learned more than I ever had in high school. You are a hero to all students with incompetent science teachers!
CONGRATULATIONS! Great visuals/animations in the series. Amazing work as always, Paul!
Dr. Andersen, I have watched your videos since AP Biology in high school and I am now taking college chemistry and these videos are still very helpful. Thank you for all that you do!
Hell Yea, Just finished watching all your 71 videos in 42 Hours, great help man, now I'll just take the AP chem exam with only watching your videos , and will see how it goes :) Big Thank You
How'd it go?
@@iamhannahmontana1153 meh didn't break any records you know :D
@@winedragon at least passing?
AP Chem Test tomorrow after graduating a semester early from highschool, I feel soooo much ready now after watching all 71 videos and taking notes!!! If you guys find this series early on I'd recommend AT LEAST two weeks before the exam to bingewatch all of the videos and take good notes (and then if you want binge-watch all Crash Course Chemistry videos and do the same), then go to khan academy to do a bunch of practice and the day or two before the exam to re-watch the entire playlist again! Thank you Mr.Andersen you explained this a lot better than most teachers!
Paul you're a damn saint. Thank you for these videos because I feel so much more prepared for the AP chemistry exam than I did a few hours ago.
Your videos have always helped in understanding these concepts. There's lots of video's, but for some reason I understand it best if you explain the concepts, a very big help! So thank you very much for making them :)
Thanks for posting this video. It has really helped me bring together several concepts for an overall better understanding of the relationship between Free energy and the Equilibrium Constant as it relates to chemical reactions.
Thanks for all excellent videos. Thank you Mister Anderson.
Just finished watching all 71 videos in this playlist for my exam tomorrow!
Thank you so much for this. Much appreciated Mr. Anderson!
I have an AP Chemistry Exam tomorrow.....actually have a chance of passing it now that I've watched every single one of these amazing videos. Thank you for everything that you do.
Good job Mr Andersen!
This guy knows everything. Thanks for the great bio and chem videos. Your bio videos helped me study to get an A+ in college honors bio!!
Please give Mr. Andersen an award!!! Thank you for the series. Please make more content on Science. The NGSS videos were great as well.
Thank you Mr. Anderson! Your videos are really really helpful!
I am going to watch them again and make some notes to review.
I've watched all of 71 of these videos for review so thank you!
This is an EXCELLENT video - thank you.
Thank you very much for all 71 of dem videos. Yes, it was helpful x71. :)
My heart stopped for a fraction of second when you said "last video". 😂
This is a great video. Thanks for explaining it this way. I never had it explained like this and it is very useful
I'm from an Arabic country. I have a very important exam tomorrow and I didn't have anyone to explain what's Gibbs free energy or what's the chemical equilibrium . I watched all your videos about the thermodynamic system and the chemical equilibrium and you can't imagine how much you helped me to understand. I'm really thankful ❤
So awesome, thank you so much for all your videos! I do hope you make more!
Excellent series as are Professor Anderson's other works. If he is not a Professor he should be. Thanks for taking the time to make these very informative videos. Mark Davis, MD.
Thanks you so much, Mr. Andersen!
Thank you very much for making these videos. These videos have assisted me very much.
Finally🙌🏽 I've watched all of the videos, I hope I do well on the ap test tomorrow
Excellent video series that has kept me busy this past week. Now it's time to check out Crash Course Chemistry!
This playlist is the entire thing I've used to study for the chem test tomorrow. Let's hope it works.
Thank you so much! Please keep making videos on other topics!
Thank you so much mr.Anderson, it is awesome
Why, thank you very much.
AP Chemistry exams tomorrow, and I finished watching this whole series over the period of 2 days....
Good luck to everybody taking it! :D :D
YOUR THE BEST MR. ANDERSON!!!!
You are a good teacher. Thank you sir.
Wow. I finished all the videos to help me prepare for the exam. It's been real, y'all.
blippetyblip same! I hope they help...
Thanks, Mr. Andersen! One fewer exam to be stressed about now.
Really really useful and clear!! Thank you SO much
Good luck on this year's AP Chem everyone!!! Anyone else here last minute??
Oh boy you don't even know haha
Yes it was enormously helpful !
YOU'RE HONESTLY THE BEST! ITS SATURDAY AND MAY 1ST IS MONDAY
I FEEL SO MUCH MORE PREPARED. THANK YOU. I CANT THANK YOU ENOUGH ACTUALLY.
SAME
Good luck to you!

you're so amazing!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I love the visuals
SOO much more helpful than Rice University gen chem profs . Thank you so much
Thank you.
Favourited.
This is WHAT'S UP!!!!! Thank you.
thank you so much for this knowledge
Why are u so awesome dude😌.? Ur teaching is excellent
you're awsome man. thanks, for your videos
thanks we hope to see in more videos
Perfect explaination.....u r a gud teacher bud🤘
I love this man!
Thankyou this was great!
Could you please cover organic chemistry, specifically the reactions of the Halogenoalkanes and Alcohols.
Great Great Video!!
very nice videos! extremely helpful; would totally recommend to a friend that's looking for a good video review :D
THAT WAS HELPFULL
Amazing! Thanks!!
very very helpfull. Thank you!
Top notch!
YES. HELPFUL. ALL OF IT.
it's very helpful to me,thx Sir
THANK YOU SIR
God bless you man
Thanks for uploading this informative video. Is there any relationship between equilibrium constant and heat capacity? Is it possible to estimate the infinite dilution heat capacity of one component if the equilibrium constant and heat capacities of other reactants and products are known?
Wow sir! It helped me a lot. Please keep making videos and I subscribed Now.. I really want videos sir!
you are so amazing
youre the best !
Thank youu. Thank youu. Thank youuuuu
Thank you
Hello! I because a little confused around 2:00. Does that mean whenever K>1, we have an exergonic, exothermic reaction? Are all endothermic reactions also endergonic?
thank you
You explained the link between these concepts well mathematically but not intuitively. How actually (at the physical/chemical level) can reactant/product concentrations affect delta G? E.g., is there some sort of modulation of entropy? I have no idea! Maths has never "explained" anything to me, just rules for a numbers game.
cleared my doubt
Is this part of your job?
I mean you put in alot of hours of video time and the time with setting up what u present n talk about.
Thanks for the video its great.. All of them are
Pls how can I calculate standard free energy Change for a reaction conducted at different temperatures but under non- standard conditions. I have got the value for enthalpy change & entropy change from van't Hoff analysis. I have also got the values of free energy change at the different temperatures. I need help pls
you saved my gpa!!!!!!!
Isnt delta G zero for rcns at equilibrium then is the G used in questions for the forward reactions to reach equilibrium?
thank you! yeah science! yes mr. A 🤓💯
HI Bozeman Science, I was wondering, can you say at the completion of the reaction, what is the concentration in grams of the products and what is the concentration in grams of the reactants. If the concentration of the products is greater than the concentration of the reactions then it is an exergonic reaction and energy is released into the surroundings. if the concentration of reactants at the end of the reaction is greater than the concentration of the products, then it is an endogonic reaction and energy is required to make the reaction occur. delta G is a measurement of the amount of energy lost from the beginning of the reaction to the end of the reaction for the exergonic reaction and delta G is the measurment of the amount of energy gained into the products from the beginning energy of the reactants.?
great techear
My teacher assigned these in quarantine.

Hi, I'm confused with the value of K, you mentioned the value of K can be neg or pos? I thought K = equilibrium constant can't never be a negative number rather it can be a very very small number but it'll still be positive (K
Michael C No he says that delta g (gibbs free energy) can be negative or positive. K can only be positive.
You said K constant here is Kc. But some questions accepts K as Kp in this formula. However Kp and Kc are different from each other. So I am a bit confused :/
I had a question on a quiz yesterday that said. Delta G standard is equal to zero at equilibrium, true or false? I said true and got it wrong. Obviously I was like WTF..!? I messaged my professor and he said I need to understand the difference between delta G and delta G standard so I'm going to his office Monday morning to settle this mess out.
Not all heroes wear capes... In this case they wear glasses and button-down plaid.
I was good until he said at 5:51 that positive change in G was exergonic??? negative Gibbs free energy is exergonic...soo I don't understand the end
omggggg, your last veideo¡ooo ,y ahestetic posing teacher will be soo saddd
he got 2 hrs of my chem lecture in 6 minutes bro
i am in grade 11 what is this??
Good luck to all of you who are taking the exam tomorrow, I think I'm looking to get a 4. If I remember, I'll reply with my score.
What did you get?
@@erinmartin1646 I got a 4! Exactly what I was hoping for. I was able to skip a chem class in college thanks to it!
@@Oliwolf78 Nice! Im taking AP chem next year, I hate science with a passion so I’m hoping I pass it so I can skip a class in college.
@@erinmartin1646 I actually loved chem and science, but it was still difficult haha. Good luck with AP chem though! It's one of the hardest AP tests, but that makes it feel all the more rewarding when you ace it.
you cannot generalise a spontaneous reaction as being exothermic/exergonic for example ice melts spontaneously at temperatures greater than 273K an endothermic reaction. therefore a reaction is spontaneous or not it depends on the environment as well as the bond forming and breaking. so whether a reaction is spontaneous or not it depends on the entropy of a reaction. as the universe as a whole moves towards more entropy, the entropy of the system as well as the universe must be taken into account when deciding if a reaction is spontaneous or not. for example with the ice melting the reaction is endothermic but the disorder of the H2O is increasing as water melts as the formation of a greater number of microstates of the water is allowed. therefore the reaction increases the overall entropy of the universe and the reaction is spontaneous.
