Choose the correct option.
For a spontaneous reaction E°_(cell) and Δ G° will be respectively:
For a spontaneous reaction $E^\circ_{\text{cell}}$ and $\Delta G^\circ$ will be respectively:
- (a)-ve and -ve
- (b)-ve and +ve
- (c)+ve and -ve
- (d)+ve and +ve
Answer
Answer
Correct option: (c)
Answer: (c) +ve and -ve
Since $\Delta G^\circ = -nFE^\circ_{\text{cell}}$, a positive $E^\circ_{\text{cell}}$ gives a negative $\Delta G^\circ$ for a spontaneous reaction.
