Calculate standard cell potential (E°), Gibbs free energy (ΔG), or use the Nernst equation for an electrochemical cell.

Formulas:

Gibbs Free Energy (ΔG):

ΔG = -n × F × E

- n = number of electrons
- F = Faraday constant ≈ 96485 C/mol
- E = cell potential in volts (V)
- ΔG < 0 : Spontaneous reaction
- ΔG > 0 : Non-spontaneous reaction
