Haber’s Process

Haber’s Process, which is also called the Haber-Bosch process, is used in the synthesis of ammonia from nitrogen and hydrogen. The Haber process to produce ammonia was developed during World War 1 (1914-1918) by a German chemist named Fritz Haber and his assistant in a laboratory. Later, in 1910, Carl Bosch took this idea and created a large-scale industrial machine for ammonia production.

In this article, we will learn What is Haber Process, the Diagram of Haber Process, equations, and thermodynamics involved in Haber’s Process.

What is Haber’s Process?

Haber Process is the industrial process for the manufacturing of Ammonia from hydrogen and nitrogen. Hydrogen is obtained from the reaction of methane and steam, producing carbon monoxide as a by-product. The hydrogen produced from this reaction also reacts with oxygen from air, producing water and leaving nitrogen behind. These gases are then compressed and delivered to the reactor where ammonia is produced. These gases are then cooled down, and ammonia is liquefied, ready to be tapped off. Unused hydrogen and nitrogen are recycled back to the reactor....

The Haber Process happens with high pressure, high temperature, and the presence of a catalyst. These conditions are necessary for conducting the reaction and ensuring the efficient production of a sufficient quantity of ammonia....

Thermodynamics of Haber Process

Whether a catalyst is present or not, the production of ammonia in the Haber-Process is a spontaneous reaction (∆G < 0). There is need to notice that the kinetics and thermodynamics of a reaction are often independent, meaning a thermodynamically favourable reaction might not necessarily be faster. The Haber-Process is an example of this, showing a reaction with favourable thermodynamics but slow kinetics....
