Question

The following concentrations were measured for an equilibrium mixture at 500.K:

Concentration of N_2(g) = 0.041 M

Concentration of H_2(g) = 0.082 M

Concentration of NH_3(g) = 0.051 M

The balanced reaction is as follows:

N_2(g) + 3 H_2(g) ⇌ 2 NH_3(g)

Calculate the equilibrium constant, Kc, at 500.K for the reaction.
