The Haber process is used in the manufacture of ammonia from nitrogen gas and hydrogen gas.
N2(g) + 3H2(g) &rlhar 2NH3 (g) ΔH = -92kJmol-1
Using Le Chatelier's principle, the best conditions for a high yield is a low temperature and high pressure. Both will push the equilibrium to the right.

Key terms in this lesson
- Catalyst
- A substance that increases the rate of a chemical reaction without being used up, by providing an alternative reaction pathway with a lower activation energy.
- Le Chatelier's principle
- The principle that when a system at equilibrium is subjected to a change, the system readjusts to minimise the effect of that change.
