<P> The reaction rate or rate of reaction is the speed at which reactants are converted into products . For example , the oxidative rusting of iron under Earth 's atmosphere is a slow reaction that can take many years , but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second . For most reactions , the rate decreases as the reaction proceeds . </P>
