5.6.1.1 Calculating rates of reactions
| Content | Key opportunities for skills development |
|---|---|
The rate of a chemical reaction can be found by measuring the quantity of a reactant used or the quantity of product formed over time: |
The quantity of reactant or product can be measured by the mass in grams or by a volume in cm³.
The units of rate of reaction may be given as g/s or cm³/s.
Students should be able to:
MS 1a Recognise and use expressions in decimal form. MS 1c Use ratios, fractions and percentages. MS 1d Make estimates of the results of simple calculations. MS 4a Translate information between graphical and numeric form. MS 4b Drawing and interpreting appropriate graphs from data to determine rate of reaction. MS 4c Plot two variables from experimental or other data. MS 4d Determine the slope and intercept of a linear graph. MS 4e Draw and use the slope of a tangent to a curve as a measure of rate of change. |
