1

Faradays equation

I * T = n * F

I = current
T= seconds
n=moles
F= farradays constant = 10^5

2

Cells full potential

Ecell =Ered + Eox

3

Gibbs at standard state for an Ecell

(delta)G = -nFE
n= moles
f= Faradays constant= 10^5

4

standard voltage of a electrochemical cell to equilibrium constant

nFE = RT ln(keq)
n=moles
T=temp in K
R = ideal gas constant in J/k*mol
F= Faradays constant = 10^5

5

Voltage of an electrochemical cell not at standard conditions

nFE = -RT ln(Q/K)

6

Kw at STP

[OH-] *[H30+] =10^-14

7

pH

-log(H+)

8

What standard pressure?

760 torr
1Atm
760mmHg
