20. Solving a chemistry problem

2. The equilibrium constant of the reaction: N2(g) 3H2(g)↔2NH3(g) ∆H=-92 kJ, equal to 0.1 (at 400 C). Equilibrium concentrations: [H2]=0.2 mol/l; [NH3]=0.08 mol/l. Calculate the initial and equilibrium concentrations of nitrogen. How will this equilibrium be affected by a decrease in: a) pressure b) temperature c) hydrogen concentration?
