The total entropy change for irreversible process is given by
(A) \( \Delta S_{\text {total }}=\Delta S_{\text {sys }}+\Delta S_{\text {surr }}=0 \)
(B) \( \Delta S_{\text {total }}=\Delta S_{\text {sys }}+\Delta S_{\text {surr }}=n R \ln V_{2} / V_{1} \)
(C) \( \Delta S_{\text {total }}=\Delta S_{\text {sys }}+\Delta S_{\text {surr }}=n R \ln V_{2} / V_{1}+C_{v} d T \)
(D) \( \Delta S_{\text {total }}=\Delta S_{\text {sys }}+\Delta S_{\text {surr }}=n R \ln V_{1} / V_{2} \)
