alleryRelation between standard cell potential E°, ΔG°, and equilibrium constant K:
AΔG° = E°/n
BΔG° = -RT/F
CΔG° = -nFE° = -RT ln K
DΔG° = nFE° = RT ln K
Answer & Solution
Correct answer: C. ΔG° = -nFE° = -RT ln K
ΔG° = -nFE° (relates ΔG° to electrochemistry) and ΔG° = -RT ln K (relates to thermodynamic equilibrium).
**So nFE° = RT ln K. Useful for predicting spontaneity and K from cell potentials.**
