Gibbs Free Energy

Question

The relationship between Gibbs free energy change and cell potential is:

RankGuru · Accepted Answer

The electrical work performed by a galvanic cell is equal to the decrease in **Gibbs Free Energy**.
- Formula: **$\Delta G = -nFE_{cell}$**
- **Where**:
- $n$: number of moles of electrons transferred in the balanced equation.
- $F$: Faraday constant (approx. $96,500 	ext{ C/mol}$).
- $E_{cell}$: the electromotive force (EMF) of the cell.
- A spontaneous reaction in a cell requires a positive $E_{cell}$ and therefore yields a negative $\Delta G$.
