Reaction Yields (AQA A-Level Chemistry): Flashcards

Amount of product if reaction goes to completion without losses

Stoichiometric ratios from the balanced chemical equation

True amount of product obtained from the reaction in practice

Usually less than theoretical yield

Transferring materials between containers

E.g., filtration causes yield loss

Form unwanted products, reducing yield

Causes actual yield to be less than theoretical

$\frac{\text{Actual Yield}}{\text{Theoretical Yield}} \times 100$

More efficient reaction
