Question
In the equilibrium A₂(g) <=> 2A(g) , if Kp = 0.5 at 400 K, what happens when the volume is doubled at constant temperature?
Explanation
Decreasing pressure (doubling volume) favors the side with more moles of gas. Here, Δ n = 2 - 1 = 1 , so the equilibrium shifts to the right (towards A ).
