the synthesis reaction of ammonia from nitrogen to hydrogen in the Haber- Bosch process is what

The synthesis reaction of ammonia from nitrogen and hydrogen in the Haber-Bosch process is a chemical reaction that forms ammonia gas (NH3) from its constituent elements. The reaction is commonly referred to as the ammonia synthesis reaction and is represented by the following equation:

N2 + 3H2 -> 2NH3

In this reaction, nitrogen gas (N2) reacts with hydrogen gas (H2) in the presence of a catalyst (usually iron) and under high temperature and pressure conditions to yield ammonia gas.
