This equilibrium is established when ammonia is made by the Haber process. $\text{N}_2 + 3\text{H}_2 \rightleftharpoons 2\text{NH}_3$ At equilibrium, the concentrations present under specific conditions are as follows. $[\text{N}_2] = 0.200\ \text{mol dm}^{-3}$, $[\text{H}_2] = 0.300\ \text{mol dm}^{-3}$, $[\text{NH}_3] = 0.600\ \text{mol dm}^{-3}$ What numerical value does $K_c$ have under these conditions?
