Assertion (A): Larger the value of cryoscopic constant of the solvent, lesser will be the freezing point of the solution.
Reason (R ): Depression in the freezing point depends on the nature of the solvent.

Options

A. If both assertion and Reason are true and the Reason is the correct explanation of the assertion.
B. If both assertion and Reason are true but the reason is not the correct explanation of the assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Answer

D

Explanation

`DeltaT_(f)propK_(f)*m` ,brgt `T_(0)-T_(f)prop K_(f)*m`
Thus, higher the molal depression constant, `k_(f)` of the solvent used, higher the freezing point of the solution.
