Cell reaction is spontaneous, when
- A \(E_{\text {red }}^{\circ}\) is negative
- B \(E_{\mathrm{red}}^{\circ}\) is positive
- C \(\Delta G^{\circ}\) is negative
- D \(\Delta G^{\circ}\) is positive
Answer & Solution
Correct Answer
(C) \(\Delta G^{\circ}\) is negative
Step-by-step Solution
Detailed explanation
\(\Delta G=\Delta H-T \Delta S\)
For a spontaneous celll reaction, \(\Delta H\) should be negative and \(\Delta S\) should be positive. Hence, \(\Delta G\) should be negative.
For a spontaneous celll reaction, \(\Delta H\) should be negative and \(\Delta S\) should be positive. Hence, \(\Delta G\) should be negative.
