The Haber Process An essential industrial process The Haber Process This reaction makes ammonia out of hydrogen and nitrogen. The nitrogen comes from the air (78% N).
What is ammonia? It is made industrially by reacting nitrogen with hydrogen in the Haber process. It is a reversible reaction, so it never goes to completion.
