A 4-page worksheet that provides a detailed introduction to collision theory and how it relates to qualitative reaction kinetics. This product is designed to be used as an introduction to the concept for middle to lower-high school students; more advanced students may need a product with greater detail about reaction kinetics.
I typically use this as a summary reading exercise that acts as a supporting document to my PPT presentation on types of chemical reactions and collision theory. After showing the relevant PPT slides to my students and viewing a brief video clip, I hand out this reading exercise for students to work on for the remainder of the lesson and for homework. A link to my Chemical Reactions PPT presentation is found below:
Pages 1-2 features a reading exercise on the following topics:
- Reactions that proceed slowly and reactions that proceed quickly
- What does rate of reaction mean?
- What is collision theory?
- Factors that affect the rate of reaction (table)
- Effect of temperature on the rate of reaction (with diagrams)
- Effect of concentration on the rate of reaction (with diagrams)
- Effect of pressure on the rate of reaction - in gases (with diagrams)
- Effect of surface area on the rate of reaction (with diagrams)
- Effect of catalysts on the rate of reaction (with diagrams)
- Effect of inhibitors on the rate of reaction (with examples)
Pages 3-4 feature a set of 12 short answer questions that review all main concepts found in the reading, including explaining experimental results using ideas from collision theory.
Pages 5-6 feature a full color-coded answer key for all review questions.
