Which one of the following statements for the order of a reaction is incorrect ?

Options

A. Order of reaction is always a whole number
B. Order can be determined only experimentally
C. Order is not influenced by stoichiometric coefficients of the reactants.
D. Order of reaction is sum of powers to the concentration terms of reactants to express the rate of reaction

Answer

A

Explanation

For the general reaction
`v_(A)A+V_(B)B+...rarrv_(L)L+v_(M)M...`
If the experimentally determined rate law is given by the equation:
`Rate=k[A]^(a)[B]?^(b)` ...
then we say that the reaction is of `a^(th)` order in `A` and of `b^(th)` order in `B` and the overall order of the reaction is the sum of the exponents of concentrations of all the reactants in the rate equation.
Order of a reaction with respect to a reactant can be `0,1,2,3,` and even a fraction or negative.
