AN INTRO:
Ammonia is very much important gas in the production of the things that are important in our daily world for e.g; in the production of fertilizers, for the acid-base reaction (ammonia is a basic gas), in the production of pesticides, textiles, dyes, bleaching and in many other chemical reactions.
Fritz Haber in 1913, developed a process to produce ammonia industrially by the reaction of nitrogen and hydrogen, known as Haber process.
