keq and concentration problem in chemistry

3. An initial mixture of nitrogen gas and hydrogen gas is reacted in a 2.0 L rigid container at a certain temperature by the reaction given below. 3 H2 + N2() +2 NH3(!) At equilibrium, the concentrations are H20 = 5.0 M, N2(0) = 8.0 M, and NH3(0= 4.0 M, a) Calculate Keq. b) Calculate the original concentrations of H2(g) and N28)
