MCQ

Select the incorrect expression from the following.

✓
$\Delta S_{\text {total }}<0$ (spontaneous process)
B
$\Delta G=\Delta H-T \Delta S$
C
$\Delta S_{\text {total }}=\Delta S_{\text {system }}+\Delta S_{\text {surr }}$
D
$\Delta S_{\text {surr }}=\frac{\Delta H_{\text {surr }}}{T}=-\frac{\Delta H_{\text {sys }}}{T}$

✓

Answer

Correct option: A.

$\Delta S_{\text {total }}<0$ (spontaneous process)

(a) $\Delta S_{\text {total }}<0$ (spontaneous process)
Explanation: For spontaneous process, $\Delta S_{\text {total }}>0$
$
T \Delta S_{\text {system }}-\Delta H_{\text {system }}>0-\left(\Delta H_{\text {system }}-T \Delta S_{\text {system }}\right)>0
$
