Students will learn about collision theory and reactions with different speeds then move onto two labs showing how to measure rate of reaction. Following this they produce rate graphs and answer questions to assess their understanding.
Recommended ages: 14+
Please see the preview for all worksheets
**Learning Objectives **
• Be able to explain why chemical reactions occur and state the name of this theory
• Be able to describe the two methods for measuring the rate of a reaction
• Be able to draw and interpret rates of reaction graphs
The labs require access to marble chips and 1M HCl. A link to a method detailing how to set up the experiment is given below (this method uses magnesium and HCl rather than marble chips).
