The rate law is an equation that relates the rate of reaction to the concentration of reactants.
The rate law is an equation that is normally used to show the relationship between the rate of reaction and the concentration of the reactants.
In each case, the rate laws are as follows;
a) Rate = k[O2] [NO2]^2
b) Rate =k[Cl2]
c) Rate = k[CHCl3] [Cl2]
