Ammonia is produced by the Haber process, in which nitrogen and hydrogen are reacted directly using an iron mesh impregnated with oxides as a catalyst. For the following reaction, equilibrium constants (Kp values) are seen below as a function of temperature.
N2(g) + 3 H2(g) reverse reaction arrow 2 NH3(g)
