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. Types of multiple reactions use molar flow rates and concentrations do not use conversion there are 4 classes of multiple reactions 1 parallel reactions. The average rate is just what it sounds like: the average of all the different rates of the reaction throughout the entire course of the reaction.
