Solution


Q.

Given below are two statements:

Statement I: A catalyst cannot alter the equilibrium constant (Kc) 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.                             [2025]
1 Statement I is false but Statement II is true  
2 Both Statement I and Statement II are true  
3 Both Statement I and Statement II are false  
4 Statement I is true but Statement II is false  

Ans.

(4)

A catalyst does not affect the position of equilibrium. It does not affect equilibrium constant or composition of reaction mixture.
