Answer
The theoretical yield is the amount of product we are expected to produce if we perform the reaction to completion by consuming all of the limiting reactant. This quantity depends on the limiting reactant as the limiting reactant is completely consumed and limits the extent to which we are able to complete the reaction and amount of product we are able to form.
Work Step by Step
The theoretic yield is the optimal or maximum amount of product we should be able to produce when we run a reaction to the greatest extent. However, a limiting reactant is the reactant that limits the extent of the reaction and therefore the amount of product we may form and the theoretical yield.
