Question

In Haber process $30\,L$ of dihydrogen and $30\,L$ of dinitrogen were taken for reaction which yielded only $50\%$ of the expected product. What will be the composition of gaseous mixture under the aforesaid condition in the end?

• A. 20 L ammonia, 10 L nitrogen, 30 L hydrogen
• B. 20 L ammonia, 25 L nitrogen, 15 L hydrogen
• C. 20 L ammonia, 20 L nitrogen, 20 L hydrogen
• D. 10 L ammonia, 25 L nitrogen, 15 L hydrogen

Answer 1

The Correct Option is D

The correct answer is Option D)  10 L ammonia, 25 L nitrogen, 15 L hydrogen

In Haber process 30L of dihydrogen and 30L dinitrogen were taken for reaction which yielded only 50% of the expected product.

The Haber process is the technique used to make ammonia. Ammonia is created when hydrogen and nitrogen react. Extremely exothermic in nature, this reaction produces heat as it proceeds. The result is

\(N_2 + 3H_2 \rightarrow 2NH_3\)
\(_{10L}^{1V} \, \, \, \, _{30L}^{3V} \, \, \, \, \, _{20L}^{2V}\) 

Two moles of ammonia are produced when one mole of nitrogen combines with three moles of hydrogen.
As only 50% of the expected product is formed, 
hence only 10 L of \(NH_3\) is formed. 
the composition of gaseous mixture under the aforesaid condition in the end will be-
\(H_2 = 30 - 15 = 15 \, L\)
\(N_2 = 30 - 5 = 25 \, L\)
\(NH_3 = 10 \, L\)

If the reaction contains a coefficient, we must subtract the assumed quantity multiplied by the reactant's coefficient from the supplied amount of the reactant to get the amount of reactant that is still present in the reaction.

Answer 3

The Haber Process, also known as the Haber-Bosch Process, is one of the most economically and effectively produced industrial ammonia processes. Throughout the 20th century, a German scientist named Fritz Haber and his assistant developed the Haber process catalyst and high-pressure machinery to carry out this process in a lab. In the year 1910, Carl Bosch took the idea and developed it into a tool for industrial manufacturing. This was a tremendous scientific achievement.
 

Raw Materials Used in the Haber Process 

A great illustration of how industrial chemists make use of the factors that affect chemical equilibria is the Haber-Bosch process. This is used to identify the ideal circumstances for creating a lot of goods at a fair price.

• The Haber-Bosch reaction turns nitrogen gas into ammonia by combining it with hydrogen gas. 
• This procedure, which is performed at high temperatures and pressures, makes use of a metal catalyst.

The process is as follows:

1. Air is used to supply nitrogen.
2. Natural gas and water provide hydrogen as well as the heat needed to heat the reactants.
3. During the process, the catalyst, iron, is not used up.

Haber Process

In the Haber Bosch method, hydrogen atoms obtained from natural gas are mixed in a 1:3 volume ratio with nitrogen gas received from the air.

• The gases are cycled, each pass cooling them, across four catalyst beds. 
• This procedure keeps the balance in place.
• Unreacted gases are recycled at various conversion criteria for each run.
• Most frequently, the procedure makes use of an iron catalyst. 
• It takes place between 150 and 200 atmospheres of pressure and 400 to 450 degrees Celsius in temperature.
• This process includes the removal of carbon dioxide, shift conversion, methanation, and steam reforming.
• At the conclusion of the procedure, the liquid solution created by cooling the ammonia gas is collected and maintained in storage containers.
