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).
Haber Process. The Haber Process equilibrium. The equation for this is: N 2(g) + 3H 2(g) 3(g) + 92.4 kJ. . . . and the K c expression is: The Haber Process (also known as HaberâBosch process) is the reaction of nitrogen and hydrogen to produce ammonia. The nitrogen (N 2) and hydrogen (H 2) gases are reacted over an iron catalyst (Fe 3+) and aluminum oxide (Al 2 O 3) and potassium oxide (K 2 O) are used as promoters. The reaction is carried out under conditions of 250 atmospheres (atm), 450-500 C; resulting in a yield of 10-20%: N 2(g) + 3H 2(g) 3(g) + 92.4 kJ.
