Chapter 5 rates of reactions 143 how does a chemical reaction occur all chemical reactions involve the rearrangement of atoms that are already present. Chemical reactions vary greatly in the speed at which they occur some are essentially instantaneous, while others may take years to reach equilibrium the reaction. The rate of a chemical reaction is a measure of how fast the reaction takes place so, a rapid reaction is completed in a short time some reactions may be. In this topic we explore collision theory and how it enables us to predict how different conditions will affect the rate of a reaction we also look at experimental.
