Supplying nitrogen and hydrogen
The Haber process manufactures ammonia for products including nitrogen fertilisers. Nitrogen is obtained from air, while hydrogen is commonly made from natural gas. The gases are purified before use. They are supplied in a nitrogen-to-hydrogen ratio of 1:3, matching the balanced equation N2 + 3H2 ⇌ 2NH3. The equation conserves two nitrogen atoms and six hydrogen atoms on each side.
