📏 Measuring Rate of Reaction
Rate = Amount of reactant used OR product formed ÷ Time
Common methods:
- Measure gas volume — collect gas in a syringe or over water, record volume at intervals
- Measure mass loss — use a balance to track mass decrease as gas escapes
- Measure time for precipitate — time until a cross disappears under the reaction vessel
- Measure colour change — use a colorimeter for colour intensity
Units for rate:
g/s, cm³/s, mol/s
