The Rate of a Chemical Reaction S-cool, the revision website

What is rate? Rate is a measure of how fast or slow something is. In chemistry, we speak of a rate of reaction, this tells us how fast or slow a reaction is. Why do chemists want to know the rate of a reaction? If you are making a product, it is important to know how long the reaction takes to complete, before the product is produced. Rate is a measure of a change that happens over a single
