Which statements of the following is incorrect.

Options

  1. AMolecularity of a reaction is always a whole number
  2. BOrder and molecularity of a reaction need not be same
  3. COrder of a reaction may be zero
  4. DOrder of a reaction depends upon the mechanism of the reaction

Correct answer

D. Order of a reaction depends upon the mechanism of the reaction

Step-by-step solution

Order of reaction is an experimental value can be whole number or fraction, while molecularity is a theoretical value and always whole number.
