JEE Main Chemistry question

Statement 1: The elevation in boiling point of a solution of a non-electrolyte is proportional to its molality. Statement 2: The molal elevation constant is the ratio of the elevation in boiling point to its molality.

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for AssertionCorrect
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (B)

Solution

Both statements are true: boiling point elevation is indeed proportional to molality for a non-electrolyte, and the molal elevation constant is indeed defined as . However, Statement 2 merely restates the definition of as a ratio at any one data point; it
