Ammonia is an important industrial product used to make fertilisers, explosives and dyes. It is manufactured using the Haber process. This involves a reversible reaction between nitrogen and hydrogen:
N2(g) + 3H2(g) ⇌ 2NH3(g)
The reaction can reach a dynamic equilibrium.
In the Haber process:
The conditions are chosen to ensure the process of making ammonia is as profitable as possible.
Explain why iron is used in the Haber process.
Iron is a catalyst for the reaction. It increases the rate of the reaction without being used up in the reaction.
State the reaction conditions used in the Haber process.
A pressure of 200 atmospheres.
A temperature of 450°C.
An iron catalyst.
