Haber-bosch process

Definition

The Haber-Bosch process is a method for synthesizing ammonia from nitrogen and hydrogen gases, developed by Fritz Haber and Carl Bosch in the early 20th century. This innovation allowed for the mass production of ammonia, which was essential for fertilizers, thus significantly impacting agriculture and food production during the Second Industrial Revolution.

5 Must Know Facts For Your Next Test

1. The Haber-Bosch process was developed in the early 1900s and became commercially viable in the 1910s, revolutionizing the production of fertilizers.
2. This process allows nitrogen from the atmosphere to be combined with hydrogen under high pressure and temperature, yielding ammonia.
3. The widespread use of ammonia from this process dramatically increased agricultural yields, supporting population growth in the 20th century.
4. The Haber-Bosch process is considered one of the most important chemical innovations of the modern era, playing a key role in both agriculture and industry.
5. Despite its benefits for food production, the process also has environmental impacts, contributing to soil degradation and water pollution through fertilizer runoff.
