उत्तर
The catalyst used in industrial preparation of ammonia is finely divided iron, and molybdenum is used as a promoter.
Explanation:
In the Haber process, finely divided iron acts as a catalyst, increasing the reaction rate by lowering the activation energy. Molybdenum (or sometimes oxides like K2O and Al2O3) is added as a promoter to boost the efficiency and activity of the iron catalyst. Together, they maximise the industrial yield of ammonia gas at a faster rate.
