Consider the reaction:

3 H2 (g) + N2 (g) ⇋ 2 NH3 (g)

In a given reaction, the initial concentrations of reactants and product are: [H2] = 0.150 M; [N2] = 0.300 M ; [NH3] = 0.000 M

If the equilibrium concentration of H2 is 0.0900 M, what is Kc for the reaction under these conditions?

   3 H2 (g) +   N2 (g) ⇋    2 NH3 (g)

I       0.15             0.3             0

C    - 3*0.02      -0.02           2*0.02

E      0.09           0.28           0.04

Kc   = [NH3]2/[H2]3 {N2]

        = (0.04)^2/(0.09)^3 *(0.28)   = 7.84>>>>>>answer
