Question

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

• A. $\Delta G$ is positive
• B. $\Delta S_{System}$ is positive
• C. $\Delta S_{Surroundings}=0$
• D. $\Delta H=0$

Answer 1

Answer: (B), (C), (D)

$\Delta H=0$

$\Delta G=-ve,\Delta S_{system}=+ve$	Always for solution formation
$\Delta S_{surr}=0$	No heat exchange between solution and surrounding
$\Delta H=0$	For ideal solution
