JEE Main Chemistry question

Which one of the following statements for order of a reaction is **not** correct? [IIT JEE 2005]

(A)Order can be determined experimentally
(B)Order of reaction is equal to sum of the powers of concentration terms in differential rate law
(C)It is not affected by the stoichiometric coefficients of the reactants
(D)Order cannot be fractionalCorrect

Answer: (D)

Solution

Order of reaction is an experimentally determined quantity equal to the sum of the exponents of the concentration terms in the experimental rate law, and it need not match the stoichiometric
