Ammonia, a very important industrial chemical, is produced by the direct combination of the following elements under carefully controlled conditions:
N₂(g) + 3H₂(g) ⇌ 2NH₃(g)
Suppose, in an experiment, that the reaction mixture is analyzed after equilibrium is reached, and it is found, at a particular temperature, that [NH₃] = 0.25 M, [H₂] = 3.4 × 10⁻³ M, and [N₂] = 5.3 × 10⁻⁵ M. Calculate the value of K at this temperature.
