Question

What do yon understand by the rate law and rate constant of a reaction ? Identify the order of a reaction if the units of its rate constants are :

(i) L^-1 mol s^-1 

(ii) L mol^-1 s^-1

Answer 1

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 each reactant is unity. 

(i) Zero order 

(ii) Second order
