Chemistry-Van't Hoff Factor

NEET Chemistry Van't Hoff Factor Assertion Reason Question

Type: Assertion Reason-assertion-Hard-Class 12

Assertion (A): The van't Hoff factor for KCl in aqueous solution is approximately 2. | Reason (R): In dissociation, the number of particles increases, leading to a van't Hoff factor greater than 1.

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 van't Hoff factor for KCl is close to 2 due to complete dissociation into K+ and Cl- ions, which increases the number of particles and thus i > 1.
