N2(g) + 3 H2(g) ↔2NH3(g)
Starting with initial concentrations of 0.400 M and .600 Mconcentrations of nitrogen and hydrgon respectively, the abovereaction is allowed to come to equilibrium. It is found that theequilbrium concentration of NH3 is 0.149 mol/L. What is the equilibrium concentration of N2 ?
