MCQ

Benzene and naphthalene form an ideal solution at room temperature. For this process, the true statement$(s)$ is (are)

$(A)$ $\Delta G$ is positive $(B)$ $\Delta S _{\text {system }}$ is positive

$(C)$ $\Delta S _{\text {surroundings }}=0$ $(D)$ $\Delta H =0$

A
$(A,B,C)$
B
$(A,B,D)$
C
$(A,C,D)$
✓
$(B,C,D)$

✓

Answer

Correct option: D.

$(B,C,D)$

d
$\Delta G =- ve , \quad \Delta S _{\text {sytem }}=+ ve \quad \text { Always for solution formation. } $

$\Delta S_{\text {surr }}=0 \quad \text { No heat exchange between solution and surrounding. } $

$\Delta H =0 \quad \text { For ideal solution. } $
