The Haber process is one of the most important industrial chemical processes and a key topic in the AQA GCSE Chemistry specification. It involves the manufacture of ammonia from nitrogen and hydrogen, and is an excellent example of how the principles of rates of reaction and equilibrium are applied in industry. This lesson covers the reaction, the conditions used, the reasons for those conditions, and the economic and environmental significance of the process.
The Haber process is the industrial process used to manufacture ammonia (NH3) from nitrogen (N2) and hydrogen (H2).
The equation is:
N2(g) + 3H2(g) <=> 2NH3(g)
This is a reversible reaction. The forward reaction is exothermic (releases energy).
| Component | Source |
|---|---|
| Nitrogen (N2) | Obtained from the air (the atmosphere is about 78% nitrogen) by fractional distillation of liquid air |
| Hydrogen (H2) | Obtained from natural gas (methane, CH4) by reacting it with steam: CH4 + H2O --> CO + 3H2 |
