The average rate of reaction is an average rate, obtained by taking the change in concentration over a time period.
For example: -0.3 M / 15 minutes
The rate at which chemical substances react varies greatly.Usually, a reaction rate involves the change in the concentration of a substance over a given period of time.
Mathematically, the rate of reaction can be calculated by dividing the change in concentration by the elapsed time.
The rate of a reaction can be graphicallycalculated by finding the slope of the concentration curve.
