Q6 / 75 · JEE Main 2025 (3 Apr Shift 1) · Chemistry

Given below are two statements
Statement I : A catalyst cannot alter the equilibrium constant $\left(\mathrm{K}_{\mathrm{c}}\right)$ 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

  • A
    Statement I is false but Statement II is true
  • Correct answer
    B
    Both Statement I and Statement II are true
  • C
    Both Statement I and Statement II is false
  • D
    Statement I is true but Statement II is false

Solution

A catalyst can change equilibrium composition if it is added at constant pressure, but it can not change equilibrium constant.

Hence, the correct answer is option: 'B'.
