Formula :
Where;
E cell = potential of electrode
E° cell = standard potential of electrode
R = Gas constant ( 8.314 J K-1 mole-1 )
n = number of electrons gained during electrode reaction
T = Temperature
F = Faraday’ s constant
K = equilibrium constant
For example ; for general electrochemical reaction.
