Cells at Non-standard Conditions (2)

Eo only applies to [ ] = 1 M for all aqueous species

at other concentrations, the cell potential differs

Ecell can be predicted by Nernst equation

n = # e- transferred

F = Faraday’s constant

= 9.6485 x 104 J/V•mol

Q is the REACTION QUOTIENT (recall ch. 16, 20)
