About the Electrochemical Cell Potential
The standard cell potential E°cell = E°cathode − E°anode. A positive E°cell means the reaction is spontaneous under standard conditions.
ΔG° = −nFE°cell links electrochemistry to thermodynamics.
How it works
E^\circ_{\text{cell}} = E^\circ_{\text{cathode}} - E^\circ_{\text{anode}}
