Q. For the process $A\left(1,0.05 \,atm , 32^{\circ} C \right) \rightarrow A \left(g, 0.05 \,atm , 32^{\circ} C \right)$
The correct set of thermodynamic parameters is

KEAMKEAM 2017Thermodynamics

Solution:

(i) $\because n$ and $T$ are constant.

$\therefore \Delta G =0$ i.e.

System is equilibrium

(ii) $\because P \rightarrow$ decreases

$\therefore \Delta S \rightarrow$ increases i.e. $(+) ve$

$\therefore $ Correct answer is $\rightarrow (B)$
