Yield & Atom Economy (AQA GCSE Chemistry): Flashcards

Amount of product obtained from a reaction

Maximum possible product from starting reactants

No atoms are gained or lost

What you actually get from the experiment

Actual is nearly always less than theoretical

Some product changes back into reactants

Some reactants left unreacted

Reactants make other unwanted products

Product lost when separating from mixture

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

No expected product was made

All expected product was made (perfect result)
