A sample of ammonia gas was allowed to come to equilibrium at 400 K

2NH3(g)  N2(g) + 3H2(g)

At equilibrium, it was found that the concentration of H2 was 0.0591 M, the concentration of N2 was 0.0197 M, and the concentration of NH3 was 0.441M.  What is Kc for this equilibrium?

Thank you for the opportunity to help you with your question!

kc = 0.0197 * (0.0591)^3/ 0.441^2

=2.1 * 10^-5
