How do theoretical yield and actual yield differ?
ATheoretical yield is measured and actual is predicted
BTheoretical yield is in moles and actual is in grams
CTheoretical yield is predicted and actual is obtained
DTheoretical yield is smaller than the actual yield
Answer & Solution
Correct answer: C. Theoretical yield is predicted and actual is obtained
1. Theoretical yield is calculated from the stoichiometry of the balanced equation.
2. Actual yield is the amount of product genuinely collected from the experiment.
3. Actual yield is usually the smaller of the two.
4. Side reactions, incomplete reactions and losses during collection all cut the actual yield.
5. Either yield may be expressed as a mass or as a molar amount, so units are not the difference.
