Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
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.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.
Correct Answer: D
Solution :
\[\Delta {{T}_{f}}\propto {{K}_{f}}.m\] \[{{T}_{0}}-{{T}_{f}}\propto {{K}_{f}}.m\] Thus, higher the molal depression constant, \[{{K}_{f}}\] of the solvent used, higher the freezing point of the solution.
