Q

How does the Haber Process work

A

The Nitrogen and the Hydrogen are pumped through the pipes. The mixture of gases are increased to 200 atmospheres. It is heated to 450C and passed through a tank containing an Iron Catalyst. The reaction mixture is cooled so Ammonia liquifies and can be extracted.
