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.
4) Mass of product: Since the limiting reagent determins how much product is formed we use the moles of limiting reagent to determine the moles and mass of product: 5) Excess mass of reactant: !.56 moles of O2 was initially present and 0.63 moles were consumed in the reaction.ince we need 2 moles of B to completely react with 1 mole of A, we will run out of B first (there is only one mole of B available). Whatever reactant runs out first is called the limiting reactant or limiting reagent.
