Question:
Which of the following is used as a catalyst in the Haber process?
Which of the following is used as a catalyst in the Haber process?
Show Hint
In the Haber process, iron acts as the main catalyst, while other oxides act as promoters to increase surface area and efficiency.

The Correct Option is A
Solution and Explanation
Step 1: Understand the Haber process.
The Haber process is used for the industrial synthesis of ammonia from nitrogen and hydrogen: \[ \text{N}_2 + 3\text{H}_2 \rightleftharpoons 2\text{NH}_3 \]
Step 2: Identify the catalyst.
The catalyst used in this process is finely divided iron, often promoted with potassium oxide (\(\mathrm{K}_2\mathrm{O}\)) and aluminum oxide (\(\mathrm{Al}_2\mathrm{O}_3\)) to increase efficiency.
