2. Consider the ammonia synthesis reaction N2(g) + 3H2(g) 2NH3(g). A mixture of N and H2 at stoichiometric molar ratio (i.e., 1:3) are placed in a catalytic reactor at T = 400 K and p = 2 bar. Find the mixture composition at equilibrium. Assume ideal gas behavior. For this reaction, AG = -11.96 kJ/mole at 400 K.
