Haber Bosch Process: Definition, Equation & Environmental …
The process combines a single nitrogen molecule with 3 hydrogen molecules to produce 2 molecules of Ammonia. The chemical equation for the Haber-Bosch process is. N 2 + 3H 2 ⇌ 2NH 3. The ⇌ arrow in the above equation implies that the reaction is reversible in nature. The reaction also happens to be exothermic.

Haber_process
The Haber process (also known as Haber–Bosch process) is the reaction of nitrogen and hydrogen, over an iron-substrate, to produce ammonia. [1] [2] [3] 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 gas is relatively inert due to the ...

Haber-Bosh Process
The production of ammonia (NH 3) from nitrogen (N 2) and hydrogen (H 2) gases occurs according to the Haber–Bosh process ( Eq. 11.vii ). This is a high-pressure, high-temperature chemical reaction that requires fine particulates of modified iron oxide as a catalyst. N 2 and H 2 are passed over the catalyst and NH 3 is subsequently formed.
