Question

$CC{l}_4$ and acetone form a non-ideal solution at room temperature in a copper container. For this process the true statement(s) is/are:

• A. $\Delta G$ is positive
• B. $\Delta S_{system}$ is positive
• C. $\Delta S_{surrounding}<0$
• D. $\Delta H>0$

Answer 1

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

The correct options are
B $\Delta S_{system}$ is positive
C $\Delta S_{surrounding}<0$
D $\Delta H>0$

$\Delta G=-ve,\Delta S_{system}=+ve$ Always for solution formation.
$\Delta S_{surr}.<0$ Heat absorbed by solution from surrounding.
$\Delta H>0$ For this solution as $CC{l}_4$ is non-polar but acetone is polar.
