Question

The ratio of hydrogen and nitrogen taken during the synthesis of ammonia is _______.

• A. 3:1
• B. 1:3
• C. 1:4
• D. 4:1

Answer 1

The correct option is A 3:1

Ammonia is industrially prepared by haber's process.
In this process both nitrogen and hydrogen gas are combined at very high pressure and temperature in the presence of spongy iron to produce ammonia.
The reaction involved is:

${\text{N}}_2\text{(g)}+3{\text{H}}_2\text{(g)}\to 2{\text{NH}}_3\text{(g)}$

Hydrogen and nitrogen are taken in a ratio 3:1 by volume.
