Statement $1$ is correct but statement $2$ is incorrect.

Vedclass · Answer

(A) Statement-$1$: At equilibrium,the system reaches a state of maximum entropy,which implies that the change in total entropy (system + surroundings) is zero,i.e.,$\Delta S_{total} = 0$. Thus,Statement-$1$ is correct.Statement-$2$: The change in entropy for a reversible process is given by $\Delta S = \frac{q_{rev}}{T}$. If the same amount of heat $(q)$ is supplied,then $\Delta S \propto \frac{1}{T}$. This means that at a lower temperature $(T)$,the value of $\Delta S$ will be higher,not less. Thus,Statement-$2$ is incorrect.

Statement-$1$: For a process at equilibrium,the total entropy is maximum and the change in total entropy is zero.
Statement-$2$: For a reversible process,if the same amount of heat is supplied to a system at two different temperatures,then the entropy change is less at a lower temperature.
