At 674.5 K the equilibrium concentrations of N2, H2, and NH3 were 0.1614 M, 0.1128 M, and 0.005892 M, respectively. What is the equilibrium constant for the reaction below?

2 NH3(g) → N2(g) + 3 H2(g)

1 answer

Substitute the equilibrium concentrations given in the problem into the Kc expression and solve for K.
