Question

State True or False.

Limiting reagent has either the least mass or the least number of moles among all the reactants available for a chemical reaction.

• A. True
• B. False

Answer 1

The correct option is B False

The statement "Limiting reagent has either the least mass or the least number of moles among all the reactants available for a chemical reaction" is false.
Limiting reagent is the reagent taken in inadequate quantity. It reacts completely but limits further progress of the reaction.
For example, consider following neutralisation reaction.
$HCl+NaOH\to NaCl+H_{2}O$.
1 mole of HCl will completely neutralise 1 mole of NaOH. If the reaction mixture contains 1 mole of HCl and 2 moles of NaOH, then HCl is the limiting reagent and NaOH is excess reagent. 1 mole of HCl will react with 1 mole of NaOH and 1 mole of NaOH will remain unneutralised.
