Which of the following statements for the order of reaction is not correct ?

Options

A. The order can be determined experimentally.
B. The order of the reaction is equal to the sum of the power of the concentration terms in different rate law.
C. It is not affected by the stoichiometric coefficient of the reactants.
D. The order cannot be fractional.

Answer

D

Explanation

The ofer of a reaction is defined as the sum total of the powers to which the various concentration terms must be raised in order to express the experimental rate low.
The order actually gives the dependence of the rate of the reaction on concentration of the reactants.
The order of a reaction is an experimentally determined quanity.
The order of a reaction can be zero.
The order of a reaction can be fractional.
The order of a reaction can be negative.
For a example reaction, the order depends on the slowest step.
The order of a reaction decides the units of rate constant of a reaction.
