Question

The cell potential $(E)$ and the free energy change $(△ G)$ accompanying an electrochemical reaction are related by:
$△ G = n F log E$
$△ G = n F E$
$△ G = - n F E$
$- △ G = n F log E$

△ G = n F log E

△ G = n F E

△ G = - n F E

- △ G = n F log E

, where

Δ G

represents maximum useful electrical work.
n = no. of moles of electrons exchanged during the reaction.
For reversible cell reaction

d (Δ G) = (Δ V) d p - (Δ S) d T

At const. P,

d (Δ G) = - (Δ S) d T

At const. P,

Δ G = Δ H - T Δ S
