Question

Why vapour pressure of a solvent is
lowered by dissolving a nonvolatile
solute into it?​

Answer 1

Answer:

Nonvolatile means that the solute itself has little tendency to evaporate. Because some of the surface is now occupied by solute particles, there is less room for solvent molecules. ... Since the solute particles do not evaporate, the vapor pressure of the solution is lower than that of the pure solvent.
