The Haber process
The Haber process involves the industrial manufacture of ammonia From Hydrogen (from methane gas) and
Nitrogen (from the air). Ammonia is used to make nitric acid which in turn reacts with ammonia to make
ammonium nitrate. Ammonium nitrate is an important fertilizer.
This reaction is a reversible reaction. The forward reaction is exothermic (meaning it gives out energy).
Nitrogen + hydrogen ammonia (+ heat).
N2(g) + 3H2(g) 2NH3(g) (+ heat)
The industrial conditions are Temperature between 450°c and 500°c, Pressure of 200atmospheres and the
use of an iron catalyst. Not most of the reactants are converted into the products- therefore, when the
ammonia is cooled down and liquefied, and removed, its remains are recycled and the process is repeated
The amount of product (yield) you get from the reversible reaction depends on the industrial conditions.
The forward reaction is exothermic
