Question:

What is the primary product of Haber-Bosch process?

Options:

Ammonia

Nitric acid

Nitrous acid

Pyridine

Correct Answer:

Ammonia

Explanation:

The Haber-Bosch process is a crucial industrial method for the synthesis of ammonia \((NH_3)\) from nitrogen \((N_2)\) and hydrogen \((H_2)\) gases. This process was developed by German chemists Fritz Haber and Carl Bosch and plays a fundamental role in the production of ammonia, which is a key component in the manufacture of fertilizers.

Here's a detailed explanation of the Haber-Bosch process:

1. Reaction: The chemical equation for the Haber-Bosch process is as follows:

\[ N_2(g) + 3H_2(g) \rightarrow 2NH_3(g) \]

2. Conditions: The reaction is typically carried out under high pressure (around 200 to 300 atmospheres) and elevated temperatures (about 400 to 500 degrees Celsius). The use of high pressure is necessary to favor the forward reaction, while the elevated temperature helps to increase the rate of the reaction.

3. Catalyst: The process often employs an iron catalyst to enhance the reaction rate. The iron catalyst provides a surface for the nitrogen and hydrogen molecules to adsorb and react, facilitating the formation of ammonia.

 

4. Purpose: The primary purpose of the Haber-Bosch process is the large-scale production of ammonia, which is a critical precursor for the synthesis of nitrogen-containing fertilizers. These fertilizers are essential for promoting plant growth and increasing crop yields in agriculture.

5. Nitrogen Fixation: The process is a form of artificial nitrogen fixation, as it converts atmospheric nitrogen, which is relatively inert, into a form (ammonia) that is more readily usable by plants.

6. Impact on Agriculture: The widespread implementation of the Haber-Bosch process has had a profound impact on global agriculture by enabling the production of synthetic fertilizers in large quantities. This, in turn, has played a crucial role in addressing food shortages and increasing agricultural productivity.

In summary, the primary product of the Haber-Bosch process is ammonia \((NH_3)\), and this process has had a significant impact on agriculture by providing a means to produce synthetic fertilizers on a large scale.
