A reaction vessel contains nh3, n2, and h2 at equilibrium at a certain temperature. the equilibrium concentrations are [n2] = 0.31 m, [h2] = 1.51 m, and [nh3] = 0.75 m. calculate the equilibrium constant, kc, if the reaction is represented as

The balanced equation for the reaction is,
          N₂(g) + 3H₂(g) ⇄ 2NH₃(g)

Since the given concentrations are taken at the equilibrium state, we can use those directly for the calculation.

Kc = [NH₃(g)]² / ([N₂(g)] x [H₂(g)]³)
Kc = (0.75 M)² / ((0.31 M) x (1.51 M)³)
Kc = 0.527 M⁻²
