How do you calculate the theoretical yield of a reaction?

To calculate the theoretical yield of a reaction, it is essential to use stoichiometry involving the limiting reagent. The theoretical yield is derived from the balanced chemical equation of the reaction, which outlines the molar ratios of reactants to products.

When conducting stoichiometric calculations, you start with the amounts of reactants you have and determine which reactant will be completely consumed first, known as the limiting reagent. This is crucial because the limiting reagent determines the maximum amount of product that can be formed, as it will be the one that runs out first in the reaction.

Once you identify the limiting reagent, you can apply the stoichiometric ratios from the balanced equation to calculate how much product can theoretically be produced from that reagent. This calculation provides the theoretical yield, which serves as a benchmark for comparing against the actual yield obtained in an experiment.

Using the boiling points of reactants or measuring the final product weight does not provide a direct method for calculating the theoretical yield. Both of those approaches do not consider the stoichiometric relationships defined by the balanced equation, which are key to determining the yield efficiently and accurately. Applying percentages of yield also falls short as it requires knowing or calculating the theoretical yield in the first place to derive a useful
