Question

At 35^oC, the vapour pressure of CS₂ is 512 mm. Hg and that of acetone is 344 mm Hg. A solution of CS₂ in acetone has a total vapour pressure of 600 mm Hg. The false statement amongst the following is :

CS₂ and acetone are less attracted to each other than to themselves.

a mixture of 100 ml. CS₂ and 100 ml. acetone has a volume < 200 ml.

Heat must be absorved in order to produce the solution 35^oC

Raoult's law is not obeyed by this system.
