DeltaG
change in Gibbs free energy
n
number of electrons per mole product
F
Faraday constant (coulombs per mole)
E
electrode potential of the reaction

Formula description

Gibbs energy is the chemical potential that is minimized when a system reaches equilibrium at constant pressure and temperature. Its derivative with respect to the reaction coordinate of the system vanishes at the equilibrium point. As such, it is a convenient criterion of spontaneity for processes with constant pressure and temperature.
