The Haber Process for Synthesizing Ammonia Fritz Haber, (1868-1934), was a German scientist who was able to synthesize ammonia from nitrogen and hydrogen gases, using osmium as a catalyst. Haber used Le Châtelier's principle in order to obtain better temperature and pressure conditions. Still, only 10 to 20% of the nitrogen and hydrogen reacted; the rest was recycled. The chemical equation Haber used to synthesize ammonia is: The laws of chemical equilibrium permitted him to predict that: 1. an increase in pressure will favour the formation of ammonia.

Unformatted text preview: 2. an increase in temperature will favour the decomposition of ammonia. 3. hydrogen and nitrogen will continue to bond as long as the produced ammonia is removed from the closed system. The ideal conditions are a pressure of 350 atm, a temperature of 500oC, a catalyst of osmium or uranium, and the ammonia must be removed from the system as soon as it is formed. The hydrogen and nitrogen react in a chamber as shown below, in order to produce ammonia....
