Δ Tf propto Kt ⋅ m T0-Tj propto Kf ⋅ m Thus, higher the molal depression constant, kf of the solvent used, higher the freezing point of the solution.

Q. Assertion: Higher the molal depression constant of the solvent used, higher the freezing point of the solution.
Reason: Depression in freezing point does not depend on the nature of the solvent.

If both Assertion: and Reason: are true and the Reason: is the correct explanation of the Assertion

If both Assertion: and Reason: are true but the Reason: is not the correct explanation of the Assertion

If Assertion: is true but Reason: is false

If both Assertion: and Reason: are false

$Δ T_{f} \propto K_{t} \cdot m$
$T_{0} - T_{j} \propto K_{f} \cdot m$
Thus, higher the molal depression constant, $k_{f}$ of the solvent used, higher the freezing point of the solution.

Q. Assertion: Higher the molal depression constant of the solvent used, higher the freezing point of the solution. Reason: Depression in freezing point does not depend on the nature of the solvent.
