Question

The number of moles of hydrogen molecules required to produce 20 moles of ammonia through Haber's process is :
(1) 10
(2) 20
(3) 30
(4) 40

Answer 1

Correct answer -3

The number of moles of hydrogen molecules required to produce 20 moles of ammonia through Haber's process is 30.

Step by step explanation:

Haber process:

• In this process combines nitrogen from the air with hydrogen derived mainly form natural gas into ammonia.

• The reaction is reversible process.

• The formation of ammonia is exothermic.

• The chemical reaction of Haber process is as follows.

$\bold{N_{2}(g)+3H_{2}(g)\leftrightharpoons 2NH_{3}(g)}$

• From the reaction, one mole of nitrogen reacts with three moles of hydrogen to form two moles of ammonia.

$2moles\,of\,NH_{3}\rightarrow 3\,moles\,of\,H_{2}$

$20\,moles\,of\,NH_{3}------------?$

$\Rightarrow 3\times \frac{20}{2}=30$

Hence, 30 moles of hydrogen forms 20 moles of ammonia.
