Cell reaction is spontaneous, when

  • A
    $E_{\text {red }}^{\circ}$ is negative
  • B
    $E_{\mathrm{red}}^{\circ}$ is positive
  • Correct answer
    C
    $\Delta G^{\circ}$ is negative
  • D
    $\Delta G^{\circ}$ is positive

Solution

$\Delta G=\Delta H-T \Delta S$ For a spontaneous celll reaction, $\Delta H$ should be negative and $\Delta S$ should be positive. Hence, $\Delta G$ should be negative.

Hence, the correct answer is option: 'C'.
