Order of a Reaction

Which of the following statemen is /are correct about order of a reaction? I. The order of a reaction can be a fractional number. II. Order of a reaction is experimentally determined quantity. III. The order of a reaction is always equal to the sum of the stoichimetric coefficients of reactants in the balanced chemical equation for a reaction. IV. The order of a reaction is the sum of the powers of molar concentration of the reactants in the rate law expression. Choose the correct option.

Assertion (A) : The order of a reaction may be defined as the sum of the powers to which the concentration terms are raised in order to determine the rate of reaction gives the total order of reactions. Reason (R) : The number of molecules whose concentrations determine the ratio of reaction at a given temperature is called order to the reaction.

For a zero order reaction, The rate becomes double when the order of the reaction.

Determination of order of the reaction

If the rate of the reaction is equal to the rate constant , the order of the reaction is
