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).
Chicago, IL. The Haber Process for the synthesis of ammonia (NH3) gas from its elements nitrogen (N2) and hydrogen (H2) is discussed in almost every high school chemistry text as an excellent example of chemical equilibrium. Very little, if anything, is said in most chemistry texts about the effects of this process on the course of history and on society.
