Nernst Equation

Postby Drew Myers 4G » Sun Mar 01, 2020 4:12 pm

What do all the variables in the Nernst equation mean?

the Nernst Equation relates cell potential with concentrations:

E = E^naught - (RT/nF)*lnQ

E^naught is the cell potential at standard conditions.
R = Gas constant
T = Temp in Kelvin
N = mols of e-
F = Faraday's constant
Q = Reaction Quotient

Another way of explaining n, is by saying it is the number of e- transferred. To find n, you would solve for the two half equations. The numbers of e- added to each equation is the n you would use. At least, that is what I understood from step up sessions.
