Question:
Catalyst used in the Haber process for ammonia synthesis:
Catalyst used in the Haber process for ammonia synthesis:
Show Hint
Haber = Ammonia = Iron. Remember "Fe-K-Al" as the trio that powers industrial fertilizer production.
Updated On: May 5, 2026
- Platinum
- V$_{2}$O$_{5}$
- Iron (with K$_{2}$O, Al$_{2}$O$_{3}$ promoters)
- Nickel
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
The Haber process is the industrial method used to produce ammonia ($NH_3$) from nitrogen and hydrogen gases.
Step 2: Meaning
Catalysts are substances that increase the reaction rate without being consumed, while promoters are added to enhance the efficiency of the catalyst.
Step 3: Analysis
Finely divided iron serves as the primary catalyst to break the strong triple bond of nitrogen. Potassium oxide ($K_2O$) and Alumina ($Al_2O_3$) are added as promoters to increase the surface area and activity of the iron.
Step 4: Conclusion
While other metals can catalyze the reaction, the specific combination of iron with these promoters is the standard industrial choice for optimal yield. Final Answer: (C)
