Of course, the time rates of change for the concentrations of the other species in the reaction are related to the rates of chemical reactions page 2-7 figure 22. The reaction rate or rate of reaction for a reactant or product in a particular reaction is intuitively defined as how fast a reaction takes place for example, the oxidation of iron under the atmosphere is a slow reaction which can take many years, but the combustion of butane in a fire is a reaction that takes place in fractions of a second.
