what is haber process?

5-2-2008Best Answer: The Haber process (also known as Haber–Bosch process) is the reaction of nitrogen and hydrogen over an iron-substrate to produce ammonia The Haber process is important because ammonia is difficult to produce on an industrial scale Even though 78 1% of the air we breathe is nitrogen the Get price

Google Answers: Understanding Catalysts and redirecting

15-6-2003Could you apply this logic (if the former was possible) to the Haber process of producing Anhydrous Ammonia where you could maybe find a catalyst to take the place of pressure and maybe heat so you could make the reaction work under more favorable less hostile working environments?
