What do you understand by the rate law and rate constant of a reaction ? Identify the order of a reaction if the units of its rate constant are :
(i) `L^(-1) mol s^(-1)`
(ii) `L mol^(-1) s^(-1)`

Explanation

The representation of rate of reaction in terms of concentration of the reactants is known as rate law. The rate constant is defined as the rate of reaction when the concentration of reactants is unity.
(i) Zero order
(ii) Second order
