What is the point of the haber process?
To turn nitrogen in the air into ammonia which we can use in many different ways for example to make fertilisers.
What are the materials for making ammonia?
Nitrogen from the air and hydrogen from natural gas.

The nitrogen and hydrogen are purified and then passed over and I am catalysts at high temperatures and pressures.
