Microbial Metabolism
The relationship between an oxidation-reduction potential difference and the standard free energy change is (where n is the number of moles of electron transferred, F= Faraday's constant and E°= standard oxidation-reduction potential difference)

ΔG° = nFlnE°

ΔG° = -nFE°

ΔG° = nFE°

ΔG° = -nFlnE°

ΔG° = nFlnE°

ΔG° = -nFE°

ΔG° = nFE°

ΔG° = -nFlnE°
