For a spontaneous process, the correct statement(s) is (are)

For a spontaneous process, the correct statement(s) is (are)
  1. $\left(\Delta G_{\text {system }}ight)_{T, p}>0$
  2. $\left(\Delta S_{\text {system }}ight)+\left(\Delta S_{\text {surroundings }}ight)>0$
  3. $\left(\Delta U_{\text {system }}ight)_{T, v}>0$
  4. None of these

Solution

For a process to be spontaneous.
$\begin{aligned} \Delta S_{\text {system }}+\Delta S_{\text {surrounding }} &>0 \\ &\left(\Delta G_{\text {system }}ight)_{T, p} < 0 \\ &\left(\Delta U_{\text {system }}ight)_{T, V} < 0 \end{aligned}$.
