### Re: 2016 Midterm Question 8C

Size of the electrode doesn't effect the cell potential, which is based ion concentration, and temperature (according to Nernst Equation, as said by midterm solutions). The Nerst Equation: E cell= E initial cell -(RT/nF)*lnQ basically shows that the size of the electrode doesn't matter: n is moles o...

### Memorization Aides

This video is a bit simplistic, but just thought I'd share a way to make O chem just a bit more fun!:https://www.youtube.com/watch?v=mAjrnZ-znkY Also here's another fun mnemonic: Monarch Edward Prefers Birthday Parties, His Highness Offers No Drinks :) for Meth- Eth- Pro- But- Pent- Hex- Hect- Oct- ...

Thanks :) I also liked https://www.youtube.com/watch?v=7qOFtL3VEBc
from the Crash Course series- they're a pretty nice summary, though simplistic.

Thanks :)

If anyone finds this acronym easier though, this is another way to remember "LEO says GER":
Lose Electron Oxidation
Gain Electron Reduction

### Re: Useful Summary of Thermodynamic Definitions

can someone elaborate on state functions? i'm still kind of confused. are they dependent or dependent? State functions are dependent on the state of the moment (temp/press/vol), but are independent of system "history"; I think it's more important to note that they are additive, like what ...

### Re: Molar Kinetic Energy?

I don't exactly know the derivation, but found this online; hope it helps! It shows a form of derivation and explains some of it. http://www.science.uwaterloo.ca/~cchieh/cact/c120/gaskinetics.html

### Re: Standard Enthalphy of a reaction

I think they would give us information to replace what is given with "standard state".
