Which one of the following statements is incorrect about order of reac...
Order of reaction is a concept in chemical kinetics that describes the relationship between the rate of a reaction and the concentrations of the reactants. The order of reaction is determined experimentally and is not related to the stoichiometric coefficients of the reactants. Let's examine each statement in detail:

a) Order of reaction is determined experimentally:
This statement is correct. The order of reaction cannot be determined by simply looking at the balanced chemical equation. It is determined experimentally by measuring the rate of the reaction under different initial concentrations of the reactants. By comparing the rate data, the order of reaction can be determined.

b) Order of reaction is equal to the sum of the power of concentration terms in the differential rate law:
This statement is correct. The rate of a reaction can be expressed using a differential rate law, which is an equation that relates the rate of the reaction to the concentrations of the reactants. The order of reaction is determined by summing the powers of the concentration terms in the rate law equation.

c) It is not affected by the stoichiometric coefficient of the reactants:
This statement is correct. The order of reaction is independent of the stoichiometric coefficients of the reactants. It is solely determined by the experimental data and the rate law equation. The stoichiometric coefficients only determine the overall balanced chemical equation, but do not affect the order of reaction.

d) Order cannot be fractional:
This statement is incorrect. The order of reaction can be fractional. In some reactions, the rate of reaction is not directly proportional to the concentration of the reactants. This can lead to fractional orders, where the power of the concentration term in the rate law equation is a fraction. Fractional orders are typically observed in complex reactions involving multiple steps or in reactions with catalytic intermediates.

In conclusion, the incorrect statement is option 'D' which suggests that the order of reaction cannot be fractional. The order of reaction is determined experimentally, is equal to the sum of the powers of concentration terms in the rate law equation, is not affected by the stoichiometric coefficients, and can be fractional in certain cases.
