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.
Any discrepancy bertween theoretical yield and practical results is due to the following causes: The reaction may not produce a stoichiometric amount of product. This could be due to equilibrium, slow rate, decomposition of reactant, or product, or evaporation. The reactants may also not be 100% pure.
