Which of the following statement is incorrect about order of reaction ...
Order of Reaction
Order of reaction refers to the power to which the concentration of reactants is raised in the rate law expression for a chemical reaction. It is an important concept in kinetics that helps in understanding the rate at which a reaction occurs.
Incorrect Statement
The incorrect statement in this question is option 'D', which states that the order of the reaction cannot have a fractional value. This statement is false because the order of a reaction can indeed have fractional values.
Explanation
- The order of a reaction is determined experimentally by studying the effect of changes in concentration of reactants on the rate of reaction.
- It is the sum of the powers of concentration terms in the rate law expression. For example, if the rate law expression is rate = k[A]^2[B]^1, then the order of the reaction would be 2+1=3.
- The order of a reaction does not necessarily depend on the stoichiometric coefficients of the reactants in the balanced chemical equation. It is solely determined by experimental data.
- Fractional orders are possible in cases where the rate of reaction is not directly proportional to the concentration of a reactant. This can occur in complex reaction mechanisms or when the reaction involves intermediates.
Therefore, it is important to understand that the order of a reaction can indeed have fractional values, contrary to the incorrect statement given in the question.
