IQ3: What affects the rate of a chemical reaction?
Students:
● conduct a practical investigation, using appropriate tools (including digital technologies), to collect data, analyse and report on how the rate of a chemical reaction can be affected by a range of factors, including but not limited to:
– temperature
– surface area of reactant(s)
– concentration of reactant(s)
– catalysts
● explain a change in reaction rate using collision theory
The first worksheet is the practical for this lesson.
The second worksheet reviews the concepts covered in this inquiry question.
Here is a simulation showing the effects of concentration, temperature and catalysts produced by The Molecular Workbench, developed in conjunction with the Concord Consortium.
