91. Solving a chemistry problem

86. When equilibrium is established N2 (g) 3H2 (g) = 2NH3 (g), the concentration of [N2] = 0.02 mol/l, [H2] = 7.2 mol/l and [NH3] = 0.8 mol/l. Calculate the initial concentration of nitrogen and hydrogen if the initial concentration of ammonia is zero. In which direction will the equilibrium shift as the pressure increases.
