Question
The standard free energy ΔG° is related to equilibrium constant K by:
- AΔG° = −RT ln K
- BΔG° = RT ln K
- CΔG° = −nFE°
- DBoth A and CCorrect
Correct answer
Both A and C
Explanation
ΔG° = −RT ln K (from thermodynamics). For electrochemical cells: ΔG° = −nFE°cell. Both expressions are valid and can be equated: RT ln K = nFE°cell.
