-2 NH? (g)  N? (g) + 3 H? (g)

Quizplus · Accepted Answer

According to Le Chatelier's principle, increasing pressure would shift the equilibrium towards the side with fewer moles of gas in order to reduce the pressure. In this case, the left side has only one mole of gas (2 NH3) while the right side has four moles of gas (1 N2 + 3 H2). Therefore, increasing pressure would shift the equilibrium to the left (←) in order to reduce the total number of moles of gas and decrease the pressure.
