Haber-Bosch Process

The Haber-Bosch process was one of the most successful and well-studied reactions, and is named after Fritz Haber (1868–1934) and Carl Bosch (1874–1940). Haber first proposed the use of a high-pressure reaction technique. Furthermore, in order to overcome the low conversion-per-pass of ammonia, he introduced an important concept: the reaction rate, ...
