Type: Assertion Reason-assertion-Easy-Class 12

Assertion (A): The elevation of boiling point depends on the number of solute molecules in a solution. | Reason (R): For dilute solutions, the elevation of boiling point is directly proportional to the molal concentration of the solute.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false.
