Question

Given below are two statements:

Statement I : A catalyst cannot alter the equilibrium constant $(K_c)$ 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

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

Answer 1

Answer: (A)

Option 1

Answer 2

A catalyst only speeds up the rate of reaching equilibrium without affecting the equilibrium constant $K_c$ or the equilibrium composition, provided the temperature remains constant. Thus, Statement I is true and Statement II is false.
