Hey there!
=>> Relative lowering of vapor pressure is a reduction in the saturated vapour pressure of a pure liquid when a solute is introduced. If the solute is a solid of low vapour pressure, the decrease in vapour pressure of the liquid is proportional to the concentration of particles of solute; i.e. to the number of dissolved molecules or ions per unit volume.
Hope it helped!!!☺️

Hey..
When a non-volatile solute is added in a volatile solvent, the V.P of solution becomes less than the V.P. of pure solvent. It is due to increase in density which decreases rate of evaporation.
