(a)
Interpretation:
The order with respect to each reactant and the overall order of the reaction have to be determined.
Concept Introduction:
The rate of the reaction is referred to the change in the molar concentration in the distinct interval of time. According to the rate law, the rate of the reaction is directly proportional to the initial concentration of the reactant of the reaction.
