Select the incorrect expression from the following.
(a) \( \Delta S_{\text {total }}=\Delta S_{\text {system }}+\Delta S_{\text {surr }} \)
(b) \( \Delta S_{\text {surr }}=\frac{\Delta H_{\text {surr }}}{T}=-\frac{\Delta H_{\text {sys }}}{T} \)
(c) \( \Delta S_{\text {total }}0 \) (spontaneous process)
(d) \( \Delta G=\Delta H-T \Delta S \)
