Question

what is limiting reagent ​

Answer 1

Answer:

Answer:

✍ Many a time, the reactions are carried out when the reactants are not present in the amount as required by a balanced chemical reaction.

✍ In such situations, one reactant is in excess over the other. This reactant which is present in the lesser amount gets consumed after sometime and after that no for the reaction takes place where be the amount of the other reactant present.

✍ Hence the reactant which gets consumed, limits the amount of product formed and is therefore called Limiting Reagent.

Note

✍ In performing stoichiometric calculations this aspect is also to be kept in mind.

Answer 2

Answer:

Definition: The limiting reactant is a reactant in a chemical reaction that determines the amount of product produced.

Examples:

Given 1 mol of hydrogen and 1 mol of oxygen in the reaction:

2 H2 + O2 → 2 H2O

The limiting reactant would be hydrogen because the reaction uses up hydrogen twice as fast as oxygen.
