Answer the following :
Name the catalyst used in Haber’s Process for manufacture of `NH_3(g). `

Answer

**Step-by-Step Solution:**

1. **Understanding the Haber Process**: The Haber process is a chemical reaction used to synthesize ammonia (NH₃) from nitrogen (N₂) and hydrogen (H₂) gases. It is a crucial industrial method for producing ammonia, which is a key ingredient for fertilizers.

2. **Identifying the Catalyst**: In the Haber process, a catalyst is used to speed up the reaction without being consumed in the process. The catalyst lowers the activation energy required for the reaction to occur.

3. **Naming the Catalyst**: The catalyst used in the Haber process is iron (Fe). It is a metal catalyst that facilitates the reaction between nitrogen and hydrogen gases to form ammonia.

4. **Additional Information**: The Haber process typically operates under high pressure (around 200 atm) and elevated temperatures (between 400-500 degrees Celsius) to optimize the yield of ammonia.

**Final Answer**: The catalyst used in the Haber process for the manufacture of ammonia (NH₃) is iron (Fe).
