JEE Main 3 April 2025, Shift 1, Chemistry Q57

Question 57 of 75 in this shift, Chemistry question 7 of 25, Section A.

Given below are two statements: Statement I : A catalyst cannot alter the equilibrium constant (Kc\mathrm{K_c}) 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. (1)Both Statement I and Statement II are true
  2. (2)Both Statement I and Statement II are false
  3. (3)Statement I is true but Statement II is falseOfficial answer
  4. (4)Statement I is false but Statement II is true
