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.
Calculating Limiting Reactant. To determine the limiting reactant, take the following steps. 1  Choose one reactant and call it A. 2  Calculate the amount of moles of the other reactant (call it B) that are needed to use up all of reactant A. 3  Compare the calculated amount of B to the actual amount available.
