Consider the following two diagram : Suppose that the solute molecules on the surface of solution occupy 10% of the surface area. The correct statement is (are)

Answer»

If the water in the vessel-I was TRANSFERRED to a container with `10%` less surface area, the vapour pressure would be lowered to same value as the vapour pressure in vessel-II.
Mole fraction of solute in container-II is `1//3`.
Boiling point solution II is `114.44^(@)C` (`k_(b)` of water is `0.52 K Kg//mol`)
If the cross sectional area of surface of solution in container-II is increased by `10%`, the number of molecules in the PHASE will INCREASE by `10%`
