A limiting reagent in a chemical reaction:

Is used up at the end of the reaction and affects the yield of the reaction significantly

Will make the reaction not obtain the maximum yield of the product.

Hinders the reaction from progressing normally

Is calculated using stochiometry

and the amounts of the reactants present.

The limiting reagent in a chemical reaction is the reactant that is completely used up at the end of the reaction. It significantly affects the yield of the reaction, as it determines the maximum amount of product that can be obtained. If any other reactants are in excess, they will not be fully utilized, and the reaction will not reach its maximum yield. The presence of a limiting reagent hinders the reaction from progressing normally, as it determines the rate at which the reaction proceeds. The determination of the limiting reagent can be calculated using stoichiometry, which involves comparing the molar ratios of the reactants in the balanced equation for the reaction.
