问题示例: For the reaction 2NO₂(g) ⇌ N₂O₄(g), an equilibrium mixture is compressed at constant temperature. What is the immediate effect on the equilibrium composition? The amount of NO₂ increases because its partial pressure decreases, The equilibrium constant decreases, The reaction quotient becomes equal to zero, The equilibrium shifts toward N₂O₄
