According to Nernst equation, which is not correct if \( \mathrm{Q}=\mathrm{K}_{\mathrm{c}} \) :
(a) \( \mathrm{E}_{\text {cell }}=0 \)
(b) \( \frac{\mathrm{RT}}{\mathrm{nF}} \ln \mathrm{Q}=\mathrm{E}_{\text {cell }}^{\circ} \)
(c) \( \mathrm{K}_{\mathrm{c}}=\mathrm{e}^{\frac{\mathrm{nFE}_{\mathrm{cell}}^{\circ}}{\mathrm{RT}}} \)
(d) \( \mathrm{E}_{\text {cell }}=\mathrm{E}_{\text {cell }}^{\circ} \)
