$At 35°C$, the vapour pressure of $C{S}_2$ is $512 mmHg$ ·and that of acetone is $344 mm Hg$. A solution of $C{S}_2$ in acetone has a total vapour pressure of $600 mm Hg$. 

The false statement amongst the following is

The vapour pressure of mixture ( $=600 mm Hg$) is greater than the individual vapour pressure of its constituents

(Vapour pressure of $C{S}_2=512\mathrm{mmHg},\text{ acetone }=344\mathrm{mmHg}$) Hence, the solution formed shows positive deviation from Raoult's law.

$\Rightarrow \text{ (a) }{\mathrm{\Delta }}_{\text{Sol }}H>0$ (b) Raoult's law is not obeyed

$\text{ (c) }{\mathrm{\Delta }}_{\text{sol }}\text{ Volume }>0$

$\text{ (d) }{\mathrm{CS}}_2$ and Acetone are less attracted to each other than to themselves.
