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