Relative Lowering of Vapour Pressure due to Non Volatile Solute

STATEMENT-1 : Relative lowering of vapour pressure is equal to mole fraction of the solute. and STATEMENT-2 : Relative lowering of vapour pressure is a colligative property.

The relative lowering of vapour pressure in case of dilute solution is directly proportional to:

Relative lowering of vapour pressure is a colligative property because
