Formation of Ammonia (Haber Process)

N2 + 3H2 → 2NH3

Ikhtisar

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.

Contoh Sehari-hari

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

Pentingnya dalam Industri

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.
