Question

37. Equal volume of N2, and H2, react to form ammonia under suitable condition then the limiting reagent is
(1) H2
(2) N2
(3) NH3
(4) No one reactant is limiting reagent​

Answer 1

Explanation:

When equal volume of react, the limiting reagent is .

Explanation:

A limiting reagent or a limiting reactant is that substance in a chemical reaction that gets completely consumed when a reaction is complete. It is important to identify a limiting reagent in a chemical reaction so that the amount of the product obtained can be calculated.

When equal quantities of react, we get the balanced equation as given below:

According to mole ratio, 1 mole of needs 3 moles of to form 2 moles of ammonia.

We are given that and are in equal quantities and so for every only 1 mole of is provided whereas 3 moles of H_2 are required to fully react.

This means that there is not enough to react with the given quantity of and so is limiting reagent.
