Formation of Ammonia (Haber Process)

N2 + 3H2 → 2NH3

Übersicht

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.

Alltägliches Beispiel

Fertilizers that feed roughly half the world's population are produced from ammonia made by this process.

Industrielle Bedeutung

The Haber-Bosch process produces over 150 million tonnes of ammonia annually, essential for fertilizers, explosives, and numerous chemical syntheses. It consumes about 1-2% of global energy production.
