The Haber process or Haber-Bosch process is the primary industrial method used to make ammonia or fix nitrogen. The Haber process reacts nitrogen and hydrogen gas to form ammonia: N 2 + 3 H 2 â 2 NH 3 (Î´H = â92.4 kJÂ·mol â1).
It is made in very large quantities and is used to then make several important chemicals inc. (nitrogen based) fertilisers. The process by which ammonia is produced is called the Haber process. This is the best method of producing ammonia (even though it is a reversible reaction). It is made by reaction hydrogen and nitrogen. Nitrogen in the Haber Process
