Given the chemical equation: N2 + 3H2 <-> 2NH3 and an initial concentration of N2 as 0.1M, H2 as 0.2M, and NH3 as 0. Calculate the equilibrium concentrations of each component at 298K if the reaction is exothermic and the pressure is increased. (Hint: Use Le Chatelier's principle to determine the direction of the shift and then use an ICE table to calculate the concentrations at equilibrium)
