Explain Freezing point depression.

The Freezing point depression is the temperature at which the liquid solvent and solid solvent are at equilibrium so that their vapor pressures are equal. When a non-volatile solute is added to a volatile liquid solvent, the solution vapor pressure will be lower than that of the pure solvent. As a result, the solid will reach equilibrium with the solution at a lower temperature than with the pure solvent.
