Rates of chemical reactions

Understanding chemical reaction rate and the factors that affect it is essential to the production of chemicals for society. Chemists use scientific equipment and apparatus  to measure rates of reactions, including measurement of mass, gas volume and time. Factors including temperature, pressure, concentration, surface area and catalysts impact rate of reaction. These factors will be explored and explained through collision theory.

This resource revises rates of chemical reactions and within rates of chemical reactions there are 2 key concepts:

• Rates of reactions
• Factors affecting rates of reaction

To determine if this resource will benefit you, start by answering the following questions:

• Why do some chemical reactions take a long time to occur, and others happen quickly?
• What are the requirements for a chemical reaction to take place?
• What factors can be changed in a chemical reaction to make it happen faster?

The answers to these questions are provided on the following pages. Use this resource to refresh your memory, reinforce your understanding of these concepts, and prepare more effectively for university-level learning.
