Statement-1 : The catalyst does not affect the equilibrium constant.
Statement-2 : Because for the catalysed reaction and uncatalysed reaction `Delta H` remains same and equilibrium constant depends on `Delta H`.

Options

A. If both the statements are true and statement -2 is the correct explanation of statement-I
B. If both the statements are true but statement-2 is not the correct explanation of statement-I
C. If statement-I is true and statement-2 is false
D. If statement-I is false and statement-2 is true.

Answer

To solve the question, we need to analyze both statements and determine their correctness based on chemical principles, particularly regarding catalysts and equilibrium constants.

### Step-by-Step Solution:

1. **Understanding Statement-1**:
- The statement claims that "the catalyst does not affect the equilibrium constant."
- A catalyst speeds up the rate of both the forward and reverse reactions equally without altering the position of equilibrium. Therefore, it does not change the equilibrium constant (K).

**Conclusion**: Statement-1 is **True**.

2. **Understanding Statement-2**:
- The second statement explains that "because for the catalyzed reaction and uncatalyzed reaction, ΔH remains the same, and the equilibrium constant depends on ΔH."
- The enthalpy change (ΔH) for a reaction is a thermodynamic property that is not affected by the presence of a catalyst. The catalyst only lowers the activation energy for the reaction but does not change the overall energy change (ΔH) of the reaction.

**Conclusion**: Statement-2 is **True**.

3. **Linking the Statements**:
- Since both statements are true, we need to assess if Statement-2 correctly explains Statement-1.
- The explanation provided in Statement-2 is valid because it correctly states that the equilibrium constant depends on ΔH, which remains unchanged by the catalyst.

4. **Final Conclusion**:
- Both statements are true, and Statement-2 provides a correct explanation for Statement-1. Therefore, the answer to the question is that both statements are correct, and Statement-2 is a correct explanation for Statement-1.

### Answer:
Both Statement-1 and Statement-2 are correct, and Statement-2 correctly explains Statement-1.
