Question

(D) The depression of freezing point occurs because the vapor pressure of the solution is lower than that of the pure solvent at the same temperature.

Vedclass · Accepted Answer

Only solvent molecules solidify at the freezing point.

Vedclass · Answer

(D) The depression of freezing point occurs because the vapor pressure of the solution is lower than that of the pure solvent at the same temperature. At the freezing point,the solid phase and the liquid phase are in equilibrium. Since the vapor pressure of the solution is lower,it reaches the vapor pressure of the solid solvent at a lower temperature. During this process,only the solvent molecules solidify,while the solute molecules remain in the liquid phase.
