Q.  The synthesis of ammonia is done by Haber's process. The reaction involved during the synthesis of ammonia (NH₃) is 
N_{2 (g)}+3H_​2(g)  $\to$2NH_3(g)

How many litres of NH₃ will be produced at STP from 20 moles of N₂? ​
(A) 696 L
(B) 796 L
(C) 896 L
(D) 996 L

Dear Student,

Please find below the solution of your asked query:

Haber's process- 

N₂ + 3H₂ → 2NH₃

Number of moles of N₂=  1 
Number of moles of H₂ =3
Number of moles of NH₃=  2

Thus, 1 mole of nitrogen reacts with 3 moles of hydrogen gas to produce 2 moles of ammonia.

So, 20 moles of nitrogen reacts with 60 moles of hydrogen gas to produce 40 moles of ammonia.

And as we know that,

1 mole of ammonia gas at STP = 22.4 L volume of ammonia gas

So, 40 moles of ammonia gas at STP = 40 * 22.4 L volume of ammonia gas

                                                           = 896 L of ammonia gas

Therefore, option (C) is correct.

Hope this information clears your doubts about the topic.

Keep asking!!
