vapor pressure lowering

vapor pressure lowering
the decrease of the vapor pressure of a solution below that of the pure solvent; the percentage change in vapor pressure is equal to the mole fraction of the solute (osmoles of solute per osmoles of solute plus solvent) and is proportional to the osmolality.
