However, in this reaction, ammonia will spontaneously, automatically, split up again into its components nitrogen and hydrogen, given by the equation:

2NH3 (g) → 3H2(g) + N2(g)

The reaction is endothermic, and again will be speeded up by an iron catalyst.

Haber Process an Example of Keq


	When both of these are put together, an essentially very simple system is set up, where nitrogen and hydrogen combine to form ammonia, and ammonia is then split up to form nitrogen and hydrogen. But how, then, is ammonia produced?
