hi! I am dyscauculic with ADHD and I've been for like, 3 years without understanding chemistry trying my hardest, usually I don't watch youtube classes cause they don't make any difference, I normally don't understand, but WOW for the first time i got something, like, in my life. I even cried a little. thank you so much, you're a hero professor!
I see below that someone pointed out that deriving the rate of the forward and backward reactions cannot be done by looking at the coefficients., but rather must be experimentally determined. The equilibrium constant can, however, be found by the coefficients. Kr and Keq are fundamentally different as can be seen if you do the work to find the units.
I have a question regarding the last problem. Why is that the reactant gained the +2x as its change in molarity when the whole reaction is product favored based on the value of Kc?
Sorry Im a little confused at 3:10 how did u derive the rate equation for the Haber process from the stoichiometric ratios? I see how you are trying to derive K from the rate constants but... the order of a reaction is not equivalent to the coefficients from the equation.
most often the rate law can be taken from the coefficients of the balanced equation, although you are correct that there are many exceptions to that, and you need to do kinetic studies to determine it. However, I did not intend to go through exceptions in a video that focuses on the basics. Equilibrium is intricately tied to kinetics. One may incorrectly think, for example, that the equilibrium expression of an Sn1 reaction is different from that of an Sn2 reaction; however, both reactions include the activity of the nucleophile in the equilibrium expression because the true full rate law of an Sn1 reaction actually includes the nucleophile and the leaving group. That is just one exception.
I feel like you confused the molarity of CCl4 to be .176 when in fact in appears to be the value we used to plug into X. CCl4 should be .024 molarity. Therefore, in the fraction where you have Kc = (2(.024))^2 / .176 ---> .176 should instead be .024.
Jeez, did i just understand this? Yes i did, sir. Thanks a lot, my book has spent around 20 pages talking about this but it makes no fucking sense. Thank you!!!!
He did this to get it into the concentration, i.e. [concentration (M or mol/L) = moles (mol)/volume (L)], since Kc is measured using the concentrations of each reactant and product. If he did not divide 0.88mol/5L to get 0.176mol/L then he would've only had the moles. He also converted the moles of CCl4 to concentration in the beginning too. Sorry if my explanation is a bit all over the place. Hope this helps
Gimme the I30N thee 8 GTI/R Killer But how can u start 5:04 😂😂😂😂 and im with you 600K for a Hatchback 5:54 yooo😂😂😂😂 i rather get an old RS3 or old A45 with +/- 150k km
Nonsense
So chemistry is nonsense to you?
Hahhahaha
the fact that this was pinned, lol
Why would you say something like that 😑😡
Don't you know that s is someone's hard work😡

glad to help!
Wooow
N1gga why'd you cry? Thats so cringe 😬😂
I never knew that I could learn the topic of 5 hrs in 12 mins ! TYSM
The one who made this video is a legend 💯
The most comprehensive video about chemical equilibrium on YT
I was very confused but after watching lots of videos and the same scenarios come up, I leaned quadratic equations and now I get it. It took a week.

Thank you allot, this will really help tomorrow in my Chemistry 1A exam.
I have a question regarding the last problem. Why is that the reactant gained the +2x as its change in molarity when the whole reaction is product favored based on the value of Kc?
this is pretty important for the AP chem test
Excellent and nicely explained. You are a good teacher.
Glad it was helpful!
this is so high quality and well explained. ty!
thank you so much, it's brief and easily understood
For the last question, why wasn't the moles(0.95) changed into molar concentration by dividing by 10L?
it is a 1.0 L container, not 10 L. If it were 10 L, we should divide by 10.
I am enjoying , bcoz of what you are explaining it is easy to understand , thank you!
literally thank u so much, this was so helpful
Do more on chemical equlibrium and titration(acid and bases)
Thank u sir ur video is too good
Please make up like this cideos
Hi!I am chiamaka pls how did u get the value of x as 0.2
I means what was the quadratic equation you used to have the value of x.Thanks
Can you please make a video about physics
Topic: simple harmonic oscillation (S.H.O)
Thank you so much, you're a life saver
You're welcome!

Why dividing the conc of NO2 BY N2O4 instead of other way round since NO2 a product not a reactant in example 2???
can you please make a video mainly on examples of questions on equillibrium
The equilibrium concentration of CCl4 must be 0.024 moles.
After struggling so much I finally found this video
plz make a video on organic chemistry
what specifically? OChem is a very big topic.
@@ketzbook
electrophillic nd nucleophillic subsitution reactions
I am finding this way more complicate than how explained in my class.. I don't understand all the x and those extra calculations here

nope, 0.176 comes right from the data in the question. It is correct.
hey..with the last question i don't get why we had -x and not +x
How do you get those initial molarities
how did u calculate initial molarity and equilibrium molarity

amazing explanation. thank you!
Good
Can you please make a video on hydrogen and proton nmr spectrum
Are you from which Country?
Good & helpful explain👍
This video help me a lot to understand this subtopic more
Thank you
Jeez, did i just understand this? Yes i did, sir. Thanks a lot, my book has spent around 20 pages talking about this but it makes no fucking sense. Thank you!!!!
Surprisingly...my lecturer watches your videos...uses ur concepts...and your questions too😂...I'm getting my fees back
Thanks very much!!!!
we want more and more videos
thanks from India class 11 preparation for jee mains
i think you forgot to square the molarity of NO2
Where is the 0.024 coming from??
7:45 can somebody explain what he just did here, why 0.88÷5, please explain
He did this to get it into the concentration, i.e. [concentration (M or mol/L) = moles (mol)/volume (L)], since Kc is measured using the concentrations of each reactant and product. If he did not divide 0.88mol/5L to get 0.176mol/L then he would've only had the moles.
He also converted the moles of CCl4 to concentration in the beginning too.
Sorry if my explanation is a bit all over the place. Hope this helps
Thanks a lot sir
you're welcome!
Is this for class 12?
Thanks
you're welcome!
Thanks for such a fine class
great!!!!
❤️❤️❤️❤️❤️❤️
You are great but 2.8+4.4=6.12and you say that it is 2+2+1.6=5.6

Pls I understand nothing
Gimme the I30N thee 8 GTI/R Killer
But how can u start 5:04 😂😂😂😂 and im with you 600K for a Hatchback 5:54 yooo😂😂😂😂 i rather get an old RS3 or old A45 with +/- 150k km
