E = E° - (RT/nF)ln(Q)

At 25°C: E = E° - (0.0257/n)ln(Q)

Or: E = E° - (0.0592/n)log(Q)

E = electrode potential under actual conditions

E° = standard electrode potential

R = gas constant (8.314 J/(mol·K))

T = temperature (K)

n = number of electrons transferred

F = Faraday constant (96,485 C/mol)

Q = reaction quotient
