Which of the following acts as a catalyst in the Haber process for the industrial manufacture of ammonia?

💡 Solution & Explanation

Finely divided iron serves as the primary catalyst in the Haber process for synthesizing ammonia, with molybdenum often added as a chemical promoter to enhance efficiency. Other substances like vanadium pentoxide are utilized in different industrial reactions such as the Contact process for sulfuric acid. Catalytic processes in industrial chemistry are frequently tested in general science sections.
