A container was charged with hydrogen,nitrogen,and ammonia gases at 120°C and the system was allowed to reach equilibrium.What will happen if the volume of the container is increased at constant temperature?
3H₂(g) + N₂(g)
2NH₃(g)

According to Le Chatelier's principle, if the volume of the container is increased, the system will shift to the side with fewer moles of gas to decrease the pressure. In this case, the side with fewer moles of gas is the side with hydrogen and nitrogen, so the equilibrium will shift to produce more hydrogen and nitrogen at the expense of ammonia. Therefore, choice C is the best answer.
