Ammonia ( (text {NH}_ {3})) plays an important role in the manufacturing process of fertilisers. The industrial process used to produce ammonia is called the Haber process. In this reaction nitrogen gas and hydrogen gas react to produce ammonia gas. The equation for the Haber process is:

Haber's Process for the Manufacture of Ammonia & Its Uses

The Haber process is typically carried out at pressures between 200 and 400 atmospheres and temperature of 500 o C. In the commercial production of ammonia, NH3 is continuously removed as it is produced. Removing the products causes more nitrogen and hydrogen to combine according to Le Chatelier's principle. The reaction is a reversible reaction.
