Chemistry · EQUILIBRIUM

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Addition of a catalyst to a reversible reaction does not change the equilibrium composition of the reaction mixture. Reason (R): A catalyst increases the rates of both forward and reverse reactions that pass through the same transition state by lowering the activation energy equally. In the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. (A) is true but (R) is false.
4. (A) is false but (R) is true.
