Question

What process produces ammonia?

Answer 1

$\huge\mathfrak\red{Hey\:Mate}$

The Haber Process combines nitrogen from the air with hydrogen derived mainly from natural gas (methane) into ammonia. The reaction is reversible and the production of ammonia is exothermic. The catalyst is actually slightly more complicated than pure iron.

Answer 2

Answer:

From Haber 's process ammonia is prepared

In this process hydrogen reacts with nitrogen at 450°C under 200 atm pressure in the presence of Fe as a catalyst and Mo promoter to form ammonia
