Question

limiting reagent when 10 moles of Nitrogen gas react with 10 moles of hydrogen gas to produce ammonia​

Answer 1

Answer:

Hydrogen

Explanation:

When ammonia is produced from nitrogen and hydrogen gases on industrial level, then the process adapted is called Haber process . The chemical reaction is written below

N2 + 3H2 → 2NH3

If we look at the balanced equation we can see that to 1 mole of nitrogen reacts with 3 moles of hydrogen, it means that more hydrogen is consumed than nitrogen and hence hydrogen is the limiting reactant if we had equal quantity of both reactants

Answer 2

Given:

The no of moles of Nitrogen gas, n1 = 10

The no of moles of Hydrogen gas, n2 = 10

To Find:

The limiting reagent in the given case.

Calculation:

- The balanced chemical equation of formation of ammonia is:

N2 (g) + 3 H2 (g) → 2 NH3 (g)

- According to the above reaction:

Moles of Hydrogen required to react with 1 mole nitrogen = 3

⇒ Moles of Hydrogen required to react with 10 moles nitrogen = 3 × 10 = 30 moles

- But there are only 10 moles of hydrogen present.

- Hence, HYDROGEN is the limiting reagent in the given case.
