Question
For the gas phase reaction: 2NO(g) ⇌ N₂(g) + O₂(g); ΔH = -43.5 kcal. Which one of the following is true for the reaction: N₂(g) + O₂(g) ⇌ 2NO(g)?
Answer: B
💡 Solution & Explanation
The reverse reaction, N₂(g) + O₂(g) ⇌ 2NO(g), will have ΔH = +43.5 kcal, meaning it is endothermic. For endothermic reactions, the equilibrium constant K decreases as temperature T decreases. Therefore, correct answer is B.
