Examine the statements carefully and mark the correct answer according to the instruction given below:
STATEMENT-1: The catalyst does not alter the equilibrium constant.
STATEMENT-2: Because for the catalysed reaction and uncatalysed reaction `DeltaH` reamains same and equilibrium constant depends of `Delta H`.

A

If both the statements are TRUE and STATEMENT-2 is the correct explanation of STATEMENT-1

B

The correct Answer is:
To solve the given question, we need to analyze both statements (Assertion and Reason) and determine their validity. ### Step-by-Step Solution: 1. **Understanding the Assertion (Statement-1)**: - The assertion states: "The catalyst does not alter the equilibrium constant." - This statement is **true**. A catalyst speeds up both the forward and backward reactions equally, allowing the system to reach equilibrium faster, but it does not change the position of equilibrium or the equilibrium constant (K). 2. **Understanding the Reason (Statement-2)**: - The reason states: "Because for the catalyzed reaction and uncatalyzed reaction ΔH remains the same and equilibrium constant depends on ΔH." - This statement is also **true**. The enthalpy change (ΔH) for a reaction is a property of the reaction itself and does not change with the presence of a catalyst. The equilibrium constant (K) is influenced by ΔH, but since ΔH remains constant, K also remains unchanged. 3. **Evaluating the Relationship**: - Since both statements are true, we need to check if the reason correctly explains the assertion. - The reason correctly explains why the catalyst does not affect the equilibrium constant, as it emphasizes that ΔH remains unchanged with the presence of a catalyst. 4. **Conclusion**: - Both the assertion and the reason are true, and the reason correctly explains the assertion. ### Final Answer: - Both statements are true, and the reason is a correct explanation of the assertion.
