Question

Why is the curve for the freezing of a solution different in slope from the freezing of the solvent?

Answer 1

Answer:

When a pure solvent freezes, its particles become more ordered as the intermolecular forces that operate between the molecules become permanent. ... As a result, more energy must be removed from the solution in order to freeze it, and the freezing point of the solution is lower than that of the pure solvent.
