ORDER OF A REACTION
The order of a reaction is defined as the sum of the powers of concentrations in the rate law.
Let us consider the example of a reaction which has the rate law
rate = k[A]m[B]n ...(1)
The order of such a reaction is (m+ n).
The order of a reaction can also be defined with respect to a single reactant. Thus the reaction order with respect to A is mand with respect to B it is n. The overall order of reaction (m+ n) may range from 1 to 3 and can be fractional.
Examples of reaction order :
