NEET Chemistry (general) Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): The depression in freezing point is directly proportional to the molality of the solution. | Reason (R): As molality increases, the number of solute particles per unit mass of solvent increases, leading to a higher depression in freezing point.
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.
Correct Answer
Option A
Detailed Explanation
The NCERT context states that depression in freezing point is related to molality, as shown in the calculation of freezing point depression using molality.
