http://www.csun.edu/~hcchm001/IntroChemHandouts.html. A limiting reagent is a chemical reactant that limits the amount of product that is formed. The limiting reagent gives the smallest yield of product calculated from the reagents. (reactants) available. This smallest yield of product is called the theoretical yield.
Limiting Reactants & Percent Yield. Mr. Andersen explains the concept of a limiting reactant (or a limiting reagent) in a chemical reaction. He also shows you how to calculate the limiting reactant and the percent yield in a chemical reaction.
