Amount of Substance (OCR A-Level Chemistry A): Flashcards

Study of quantitative relationships in chemical reactions

Mole ratios of substances in the reaction

$24 \text{ dm}^3$ or $24000 \text{ cm}^3$

Reactant that gets completely used up first, stops reaction

$\frac{\text{actual yield}}{\text{theoretical yield}} \times 100\%$

$\frac{\text{desired products}}{\text{all products}} \times 100\%$

Maximum amount of product if reaction goes to completion

Incomplete reactions, side reactions, loss during purification

Proportion of reactant atoms that end up in desired product

It gets used up first, so no more product can form after
