प्रश्न
In a reaction, \[\ce{A + B2 -> AB2}\]
Identify the limiting reagent, if any, in the following reaction mixture.
100 atoms of A + 100 molecules of B
उत्तर
A limiting reagent determines the extent of a reaction. It is the reactant which is the first to get consumed during a reaction, thereby causing the reaction to stop and limiting the amount of products formed.
According to the given reaction, 1 atom of A combines with 1 molecule of B. Thus, all 100 atoms of A will combine with all 100 molecules of B. Hence, the mixture is stoichiometric where no limiting reagent is present.
