For N₂(g) + 3H₂(g) ⇌ 2NH₃(g) at equilibrium, what happens when more H₂ is added at constant volume and temperature?
Correct answer C. The equilibrium shifts forward and more NH₃ forms
Explanation
By Le Chatelier's principle the system uses up some of the added H₂ by reacting it with N₂, so the position shifts to the right while Kc stays the same.
