Which catalyst is used in the industrial Haber-Bosch process for the synthesis of ammonia?
A. Finely divided iron with molybdenum promoter✓ Correct Answer
B. Nickel
C. Platinum
D. Vanadium pentoxide
💡 Solution & Explanation
The industrial Haber-Bosch process for synthesizing ammonia from atmospheric nitrogen and hydrogen utilizes a finely divided iron catalyst promoted with substances like potassium oxide and aluminum oxide. This heterogeneous catalysis significantly lowers the activation energy required for the high-pressure and high-temperature reaction.
