A chemistry student is experimenting with the reaction: N2(g) + 3H2(g) ⇌ 2NH3(g). They want to investigate the effect of pressure on the yield of ammonia. Write a problem for the student to solve using Le Chatelier's principle that will help them predict the effect of changes in pressure on the equilibrium position of the reaction.
