The Molal elevation constant depends upon

Assertion: Molal elevation constant depends on the nature of the solvent.

Reason: Molal elevation constant is the elevation in boiling point when 1mole of the solute is dissolved in 1kg of solvent.

(A) Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

(B) Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.

(C) Assertion is correct but Reason is incorrect.

(D) Both Assertion and Reason are incorrect.

Answer:

(B) Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.

Explanation:

Molal elevation constant depends on the nature of the solvent as it is characteristic of solvent.
Molal elevation constant is the elevation in boiling point when the solute is dissolved
in  of solvent

.

Here m is the molality of the solution.
