Ammonia is a critically important industrial chemical, serving as the primary precursor for nitrogen-based fertilisers, explosives, and various pharmaceutical compounds.
In industry, ammonia is synthesised via the reversible reaction of nitrogen gas with hydrogen gas.
The word equation representing this fundamental reversible step is:
nitrogen+hydrogen⇌ammonia \text{nitrogen} + \text{hydrogen} \rightleftharpoons \text{ammonia} nitrogen+hydrogen⇌ammoniaState the name of this industrial process used to manufacture ammonia.
