Question

For the reaction \( H_2(g) + I_2(g) \rightleftharpoons 2HI(g) \), the equilibrium constant \( K_p \) changes with

• A. total pressure
• B. catalyst
• C. the amount H₂ and I₂
• D. temperature

Hint:

The equilibrium constant is temperature dependent and changes with changes in temperature.

Answer 1

The Correct Option is D

Step 1: Temperature dependence of equilibrium constant.
The equilibrium constant \( K_p \) depends on temperature, as shown by the van't Hoff equation. A change in temperature alters the position of equilibrium.

Step 2: Conclusion.
Thus, the correct answer is option (D).

Final Answer: \[ \boxed{\text{(D) temperature}} \]
