Question

Ammonia fertilisers are synthesized from nitrogen and hydrogen gases at high
pressure. How can be high pressure created in gases? ​

Answer 1

Answer:

The Haber process,[1] also called the Haber–Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today.[2][3] It is named after its inventors, the German chemists Fritz Haber and Carl Bosch, who developed it in the first decade of the 20th century. The process converts atmospheric nitrogen (N2) to ammonia (NH3) by a reaction with hydrogen (H2) using a metal catalyst under high temperatures and pressures:

Answer 2

Explanation:

Due to the Haber process being a reversible reaction, the yield of ammonia can be changed by changing the pressure or temperature of the reaction.

Increasing the pressure of the reaction increases the yield of ammonia. ...

Increasing the temperature of the reaction actually decreases the yield of ammonia in the reaction.
