AP Chemistry: Thermodynamics 5

n = LCM(e-)

[srigiriraju007]

before watching your videos, i hated the chemistry the mossssssssst!!!!!! thank you chemguy, <3 <3

[pravin3783]

I don't know how to praise you Sir,

You are just AMAZING. You are probably best chemistry teacher on this earth

[09surebo]

Wow, you are awesome...I go to Dartmouth ( ranked #1 best for undergraduate teaching in America) and I'm using your videos to study for my final. You explain so much clearer than my prof lol.

[jeffc314]

=] Thank you for the video chemguy!

[DrPirate42]

I. Love. You.

You saved me on the electrochemistry section of my physical chemistry course.

I don't know how to thank you *donates to site*

[Cherivier]

finally, someone who makes sense!

[jambieyes]

Long live Chemguy!

[bannanaiscool]

I'm a high school teacher.

[gummisius]

the equilibrium constant, K, is actually the ACTIVITY of the products/ ACTIVITY of reactants, however, the concentrations of the products/reactants is used to determine Kc. Also, the Faraday's constant is also 96,485J/v^-1mol^-1. tricky redox question is: balance the following redox reaction to give the balanced half reactions and net ionic equation

HNO3(aq) + KI(aq) ---> NO(g) + I2(s) +

H2O(l) + KNO3(aq)

By thy way, this guy explains this exceptionally well. is a prof or highschool teacher?

[apocalex13]

isn't the Nernst Eq:

Ecell = E'cell - (RT/nF) lnQ ??

Doesn't the one you wrote only work at Standard conditions for concentrations that aren't 1mol/L ?

[daj4ck4as]

this is gibbs free energy.. same thing if u convert the cell potential

[akamouse213]

thats the same thing.. plug in some numbers and check it

[MaryElise2009]

Keep up the good teaching!

[icef1sh]

im going to name my first born son Chemguy in your honor.

[soradora111]

Oh my gosh I have a test tomorrow for my AP Chem class and I was so confused in some parts. Your videos totally explained everything for me. My teacher can't really explain well and only leaves me even more confused! You are AWESOME!! Thank you thank you thank you!!!

[bannanaiscool]

I'm teaching this right now to my Chem IB students in Canada!

We do this in grade 12, advanced level.

Chemguy

[cycro27]

Where are you in Canada Chemguy? You look SOOO familiar!

[jamesleixlip]

tobias funké from arrested development a.k.a david cross

[NormanBatesIsMyMum]

These are good videos! I was confused in a lecture earlier but now I realise this is fairly simple.

Chemguy - I salute you!

Also do Americans do this at school ? if so your cleverer than the stereotype, Ive only started this now half way through the first year of university!

[Jscottpekar]

Chem. Guy you're amazing. I have been watching many of your videos and they are all quite helpful! I watch them before my teacher lectures and after my teacher lectures and then once more before the quiz. Then I watched them again for the midterm and finals. The were great for review and learning. Thank you. They were a tremendous help!

[steevenikkunat]

Thank you so much!

Everything is so clear after i watched these videos! Youre awesome!

[Lorentz5]

this guy actually inspires me ...

[phoenixlament88]

The wheel cometh full circle! What an AMAZING FINALE!!

Everything in my head was in pieces 5 minutes ago. Thanks so much for putting all those pieces together!! It all makes sense now. Everything is related to everything else.

We connected Gibbs free energy to Keq and Ecell.

dG = RT*lnKeq

dG = -n(F naught)(E naught)

Now we can mix and match with amazing possibilities:

E naught = RT/(nF*lnKeq)

So so so simple! We are victorious!

Chemguy EPIC WIN!!!

[ramizkhar]

chemguy.....your AWESOME!

[joeyfung85]

thank you so much!!!!!!!!!!!!!!!!!!!!!!

[Coolnar13]

Thank you SO MUCH!

[ddrose272]

all the comments express what i wanna tell you :-)

thank u

[yragorn]

lmao he's Canadian woot!

[dorothydorothy111]

chemistry IS cool because of ChemGUY!!!

[david345223]

this guy makes chem sooooo cool!!

[windowmakers077]

Thank you sooo much for your thermodynamics series. I understand this topic better now. Thank you!!!! :)

[double89k]

u are by far the best chem teacher ive ever seen

2 thumbs up!

[shiizzlee]

Awesome.

[dalaiwtf]

brilliant!!

[GoldeWC]

thank you so much everybody give feedback 5/5

[bordway]

Well spoken.

[Bashfulll]

Very informative!

Been through all of thermodynamic clips and think the're absolutely fab.

Are you related to einstien????lol
