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).
This process produces an ammonia, NH. The Haber synthesis was developed into an industrial process by Carl Bosch. The reaction between nitrogen gas and hydrogen gas to produce ammonia gas is an exothermic equilibrium reaction, releasing 92.4kJ/mol of energy at 298K (25 o C).n 1909 Fritz Haber established the conditions under which nitrogen, N. 1  medium temperature (~500 o C). 2  very high pressure (~250 atmospheres, ~25,500kPa). 3  a catalyst (a porous iron catalyst prepared by reducing magnetite, Fe 3 O 4).
