319497 At\({\rm{35^\circ }}\,{\rm{C}}\), the vapour pressure of \({\rm{C}}{{\rm{S}}_{\rm{2}}}\) is 512 mm Hg and that of acetone is 344 mm Hg. A solution of \({\rm{C}}{{\rm{S}}_{\rm{2}}}\) in acetone has a total vapour pressure of 600 mm Hg. The false statement amongst the following is :

1 A mixture of 100 mL \({\rm{C}}{{\rm{S}}_{\rm{2}}}\) and 100 mL acetone has a volume < 200 mL
2 Roult’s law is not obeyed by this system
3 \({\rm{C}}{{\rm{S}}_{\rm{2}}}\) and acetone are less attracted to each other than to themselves
4 Heat must be absorbed in order to produce the solution at \({\rm{3}}{{\rm{5}}^{\rm{^\circ }}}{\rm{C}}\)
