JEE Main 2025 — 3 April, Morning Shift — Question 7

Given below are two statements :

Statement (I) : A catalyst cannot alter the equilibrium constant (Kc)\left(\mathrm{K}_{\mathrm{c}}\right) of the reaction, temperature remaining constant.

Statement (II) : A homogenous catalyst can change the equilibrium composition of a system, temperature remaining constant.

In the light of the above statements, choose the correct answer from the options given below.

  1. Option A:

    Both Statement-I and Statement-II are false

  2. Option B:

    Both Statement-I and Statement-II are true

  3. Option C:

    Statement-I is true but Statement-II is false

    Correct
  4. Option D:

    Statement-I is false but Statement-II is true

Answer: C

Step-by-step solution

Catalyst doesn't change Keq\mathrm{K}_{\mathrm{eq}} catalyst doesn't change composition statement-I is true

But statement-II is false.
