Q. In an irreversible process, the value of $ΔS_{\text{system}}+ΔS_{\text{surr}}$ is :

NTA AbhyasNTA Abhyas 2022

Solution:

$\Delta S_{\text {system }}+\Delta S_{\text {surr }}=\Delta S_{\text {total }}$
So if:
$\Delta S_{\text {total }}>0$, process will be spontaneous or in other word irreversible.
$\Delta S_{\text {total }}<0$, process will not happen
$\Delta S_{\text {total }}=0$, process is in equilibrium.
