Lowering in Vapour Pressure

When a non volatile solute is present in the solution, the vapour pressure of the solution will be less than vapour pressure of pure solvent.

Lowering in vapour pressure is directly proportional to the mole fraction of solute.

The relative lowering in vapour pressure is equal to the mole fraction of solute
