Question

In the Haber's process, the ratio of hydrogen and nitrogen used for the synthesis of ammonia is:

• A. 1:3
• B. 3:1
• C. 1:4
• D. 4:1

Answer 1

The correct option is B 3:1

In the Haber Process, nitrogen gas and hydrogen gas are taken in a ratio 1:3 by volume. Both nitrogen and hydrogen gas are combined at very high pressure and temperature in the presence of spongy iron which acts as a catalyst to produce ammonia. The reaction of nitrogen with hydrogen in the Haber process is as follows.

$N_2\left(g\right)+3H_2\left(g\right)\to 2N{H}_3\left(g\right)$

So, the ratio of hydrogen to nitrogen in the Haber process is 3:1.
