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

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

Solution & Step-by-step Explanation

Statement A is incorrect because the order of a reaction can be zero, an integer, or even a fraction. It is not restricted to whole numbers. Statements B, C, and D are standard correct definitions/properties of reaction order.
