Question

Lowering of vapour pressure​

Answer 1

Answer:

The vapor pressure of a solvent in a solution is always lower than the vapor pressure of the pure solvent. The vapor pressure lowering is directly proportional to the mole fraction of the solute. This is Raoult's Law.

Answer 2

The vapour pressure is the liquid of the pressure of the vapour which is in equilibrium with that liquid . The vapour pressure of a solvent is lowered when a non volatile solute is dissolved in it to form a solution .
