Why are catalysts used during the Haber process?

Answer 1

It speeds up the reaction that produces ammonia.

Answer 2

It speeds up the reaction that produces ammonia.

Answer 3

The use of catalyst can increase the reaction rate so a greater product amount can be produced in given time. Catalysts can also be reused and they lower energy costs as the reaction can occur at a lower temperature.

The most common catalyst for the Haber process is iron doped wit oxides of Al, Si, Ca or K.

It would be too dangerous (as well as too energy inefficient) to do the reaction without one.

Step 1: N2 + H2 -> N2H2

The Diazene you produce in this step is very unstable and dissociates almost immediately.

Step 2: N2H2 + H2 -> N2H4

The Hydrazine you produce in this step is dangerous in every way a chemical can be.

Step 3: N2H4 + H2 -> 2NH3

To prevent this, they use an iron catalyst. Heat it to 500 degrees C, mix nitrogen and hydrogen, pump it up to 200 atmospheres, and blow the gas across the catalyst and ammonia is safely formed...better, since the reaction is exothermic it'll generate enough heat to keep the reaction going once it's started.
