she didnt convert J of Delta S to KJ.

she talks wayyyy too fast.

[AvilesChemtutor]

Could you check the entropy value -118.0 j/mol, in the sample you used 118 kJ instead of J/K.

Good job though, I really enjoy your videos.

[uekikuske009]

how come your entropy is in the form of kJ? shouldn't it be in J/mol.K?

Thanks for making this video

GO LEFTIES

I am confused why is it that if it is not spontaneous it is suddenly a bad thing? I have not heard of that before. Could someone please explain? Or is it just a way of saying they are two very separate things. I figure spontaneous things such as flammable objects would be considered bad, not the other way around. Any help would rock thank you :)

[teperc9702]

@Cramerica66 It's not bad, just a way of differentiating. By "bad" we mean "unable to proceed in the forward reaction". Hope this helps :).

Thank you.dont worry about your talking speed I can replay it anytime :)

[TheLAPosh]

 woww she talks too fast hahaha

[curls1213]

I agree with 82tomify...lol

This was a very helpful video btw :)

[82tomify]

that is why there is a pause button

[MsJRQ]

thank u!

[MsJRQ]

thank u! 

[PlasticFunnel]

wow a cute chick teaching chem! :D

[Do2016]

Great lecture!! Thanks!

[WHY70122]

Is there any button more than 5 stars :)

************* ive made it though :D i agree with someone above that u gotta slow down a bit . Cuz this is one of the most difficult part in chem 2 i guess. I have my own favourite channels that help me with chem but for this problem...i never find those useful except this one. Thanks a lot for uploading this. And if u have time plz label ur vids with more specified details so we dont get messed trying to search ur vids...cuz before i came up with this...

[brightstorm2]

@WHY70122 Thanks for your nice words. If you go to Brightstorm site, you can find videos for your topic much conveniently. You can search with keywords, browse by topic, or even use your textbook page to find related videos.

@brightstorm2 at 3:20 did you do that math in your head if so where did you learn to day math like that in your head I am a fairly intelligent person and it took me about 3x as long to do that.

I think in the example problem the unit for dellta S was NOT converted to KJ in order to apply like terms with delta H.

[steven09652jordan]

your calculation is wrong.

[tothedeath456]

thanks your videos are good :) but you do kinda make a few mistakes - maybe watch it through before you upload it to make sure its right??

[1006Will]

YOU HAVE GOT TO SLOW DOWN. You are teaching, not narrating~ You know everything already, we don't. So that's something to improve..

[eaklile]

I may be wrong, but is not -232kj MINUS 37.7kj = -269.7? if you subtract from a negative, shouldnt the answer be more negative?

[giorga2004]

Thank you for the video, but try to slow down when speaking. I have to keep rewinding :)

[vidstudy]

thank you very much, this is the best video on youtube

[MKrell24]

Although I think this videos are really helpful (mostly because I can pay more attention when its not 8 in the morning), they have the same problem as my normal chemistry lessons in that they don't conceptually teach anything, they just show you how to do the problems. Instead of just saying that we want temp to be high when the reaction was endothermic and the change in entropy was positive, explain why thats the case. Its useless to know this stuff if you cant apply it outside of the class.

[mauzakhtar]

hey im from from Canada...love ur videos..they are really helpfull..just like to mention u forgot to conver 118 into kj,s:)
