A chemist mixes together 0.450 mol N2 with 0.450 mol H2 in a sealed container. The mixture is heated and allowed to reach equilibrium. At equilibrium, the mixture contains 0.400 mol N2 and the total pressure is 500 kPa. Calculate Kp.

balanced equation:  N2 (g) + 3H2 (g) <---> 2NH3 (g)  Both reactants and products are gases, therefore it affect Kp value. This equation reaches equi...
