A chemistry student needs to determine the effect of increasing the pressure on the equilibrium position of a reaction. Consider the following reaction at equilibrium: N2(g) + 3H2(g) ⇌ 2NH3(g) If the pressure is increased, will the reaction shift to the left or right, and in what direction will the reaction quotient, Q, shift as a result? Justify your answer using Le Chatelier's principle.
