Question

the no of moles of nitrogen gas required to produces 10 moles of ammonia in presence of hydrogen gas is mcq
​

Answer 1

Answer:

5 moles of nitrogen gas will be required to produce 10 moles of ammonia in presence of hydrogen.

Explanation:

What is the mole concept?

A mole is basically a measurement unit, which is defined as the amount of substance which contains as many 'entities' (particles/atoms/molecules) as there are atoms in 0.012 kg of Carbon (C₁₂) isotope.

Calculation of moles of N₂:

Let us first write down the chemical reaction:

N₂ + 3H₂ ⇄ 2NH₃
1         3           2

Thus, ideally, we can see that, at STP

2 moles of ammonia gas are produced from 1 mole of nitrogen gas
∴ 10 moles of ammonia gas will be produced from
$= (\frac{1}{2} \times 10)$ moles of nitrogen gas
= 5 moles of nitrogen gas

Calculation of moles of H₂:

Similarly,

2 moles of ammonia gas are produced from 3 moles of hydrogen gas
∴ 10 moles of ammonia gas will be produced from
$= (\frac{3}{2} \times 10)$ moles of hydrogen gas
= 15 moles of hydrogen gas
