Question

Why vapour pressure of the solution of a non volatile solution is lower than that of pure solvent?

Answer 1

Fewer solvent molecules can vaporize, and the vapor pressure is lower. others are solute molecules. Only the solventmolecules are volatile. ... There are fewer solvent molecules on the surface of the solution than on the surface of the pureliquid.
