Electrochemistry ❮ 259● The following relationships can be used to calculate quantitative changes that occur in
an electrochemical cell, especially an electrolytic one: 1 F = 96,500 C per mole of electron
(F = 96,500 C/mol e- = 96,500 J/V mol) and 1 amp = 1 C/s (A = C/s).
● The standard cell potential can be used to calculate the Gibbs free energy for the reac-
tion: DG° = - nFE°cell. Know how to use this equation.
● The standard cell potential can also be used to calculate the equilibrium constant for a
reaction: K
