I'm a little bit confused. Is a positive value for Total Entropy Change kinetically feasible, but a value of zero or a negative value for Gibbs Free Energy Change also feasible? If this is correct, why is this?
+James P Yes specimen papers for new spec coming soon, watch this space! I have done a back titration video for iodine and thiosulfate reaction. Here is the link ua-cam.com/video/w4tpyDLK5vA/v-deo.html
Hello, is this correct at 8:04? I think you may have subtracted by mistake. When I enter that in my calculator I get 4,469.7 JK^-1 Mol^-1 .Also at 7:05 would the value be positive or negative and why?
Hi, at the side on entropy of surroundings you've put that the delta H needs to be in kj mol-1 and in this example it has been given to you in kj mol-1 so why convert it into joules? Just a little confused haha
+lydia sheridan Yes because Entropy has the standard units of JK-1mol-1. Enthalpy has to be converted to ensure the right number is used for the Entropy total calculation.

thank you this playlist has saved my grades
Wait but it says on your equation on the right that enthalpy change is in kJ/mol so why did u convert to J?
Brilliant explanation. Thank you!

Hi! Will you go through the specimen paper at some point? Also, have you covered so-called 'back titrations'?
Thanks!

I am also getting the same answer
It is negative 208 (-208.2) + 4621 = 4052.8
Thank you!
4:17 - shouldnt it be ( 416 x 2 ) + 205 = 1037 ?
No. The value is 41.6 not 416.
@@AlleryChemistry Should write clearer. That messed me up aswell

No worries!

You're very welcome!
nice
your decimal point is so light ... just cant see it....confused me
too fussy, come on you should do better.
