Which industrial method is used to convert nitrogen gas into ammonia?

The Haber-Bosch Process is the industrial method specifically designed to synthesize ammonia from nitrogen gas and hydrogen. This process is crucial for producing ammonia on a large scale, which is then used as a key ingredient in fertilizers, helping to support global agricultural needs.

The process operates under high temperature and pressure, utilizing an iron catalyst to facilitate the reaction between nitrogen and hydrogen gases. Given the abundance of nitrogen in the atmosphere, this method becomes vital for achieving nitrogen fixation, effectively converting an inert gas into a usable form for plant growth.

Understanding the broader context of the other processes is beneficial: the Fritz Haber Process refers to the same underlying reaction as the Haber-Bosch Process but does not encompass the full industrial application, hence it is not the complete answer for large-scale production. The Contact Process is used to produce sulfuric acid, while the Solvay Process focuses on producing sodium carbonate. These distinctions clarify why the Haber-Bosch Process is the correct choice for the conversion of nitrogen gas into ammonia.
