Formation of Ammonia (Haber Process)

N2 + 3H2 → 2NH3

Visão geral

The Haber-Bosch process combines nitrogen from the atmosphere with hydrogen gas to produce ammonia. This reversible reaction requires high temperatures (400-500 C) and pressures (150-300 atm) along with an iron catalyst. It is arguably the most important industrial chemical reaction ever developed.
