What is the primary catalyst used in the Industrial Haber-Bosch process for synthesizing ammonia gas from elemental nitrogen and hydrogen?
A. Finely divided nickel
B. Iron with molybdenum promoter✓ Correct Answer
C. Platinum metal gauze
D. Vanadium pentoxide
💡 Solution & Explanation
The industrial synthesis of ammonia via the Haber-Bosch process utilizes an iron catalyst promoted with potassium oxide and aluminum oxide to enhance reaction rates at high pressures. Nickel is used in hydrogenation reactions, platinum in nitric acid production, and vanadium pentoxide in the Contact process for sulfuric acid. Catalysts lower activation energy without being consumed.
