Rate Of Reaction - GCSE Chemistry Definition

Reviewed by: Richard Boole

Published

The rate of reaction is a measure of how quickly a chemical reaction takes place. It tells us how fast reactants are turned into products.

For example, when an effervescent tablet is dropped into water, the rate of fizzing shows how quickly the reaction is happening.

Certain factors can affect the rate of reaction:

  • Temperature

  • Concentration of reactants

  • Surface area of solid reactants

  • Use of a catalyst

Understanding reaction rates is important in GCSE Chemistry for predicting and controlling chemical processes in areas like industry, medicine, and everyday life.

Richard has taught Chemistry for over 15 years as well as working as a science tutor, examiner, content creator and author. He wasn’t the greatest at exams and only discovered how to revise in his final year at university. That knowledge made him want to help students learn how to revise, challenge them to think about what they actually know and hopefully succeed; so here he is, happily, at SME.
