Chemistry
Answer
Nitrogen reacts with hydrogen under specific conditions liberating ammonia
N2 + 3H2 ⇌ 2NH3 + Δ
Conditions :
Temperature : 450-500°C [Optimum temperature]
Pressure : 200 to 900 atmospheres [Optimum pressure]
Catalyst : Finely divided iron [Fe]
Promotor : Molybdenum [Mo]
[Catalyst - iron [III] oxide [Fe2O3] may also be used containing promoters about 1% K2O and 3% Al2O3]
Precautions : Impurities like CO, CO2, and H2S may poison the catalyst hence, the nitrogen-hydrogen reactant mixture must be free from them.
