Introduction the rate of a chemical reaction is the change in concentration over the change in time and is a metric of the speed at which a chemical reactions occurs and can be defined in terms of two observables.
Therefore, the reaction rate of a chemical reaction is generally stated as 562 chapter 16 reaction rates you can also choose to state the rate of the reaction as the rate at which co is consumed, as shown below average reaction rate.
