Question

For the reaction 2NH3(g) −⇀ 3H2(g) + N2(g) , the equilibrium concentrations were found to be  [NH3] = 0.250M, [H2]= 0.580M, and [N2] = 0.750M.

What is the equilibrium constant for this reaction?

Answer 1

Keq = [H₂]³[N₂] / [NH₃]²

Just plug in the values that are given and solve for Keq.
