A student wants to know how changing the volume affects the position of the equilibrium for the reaction N2(g) + 3H2(g) ⇌ 2NH3(g). If the reaction is initially at equilibrium in a 2 L container at 400 K and then the volume is decreased to 1 L, what will be the new concentrations of each gas at equilibrium? (Assume that the pressure remains constant and that the reaction follows the ideal gas law.)
