What is the primary difference between order and molecularity of a reaction?

Options

  1. AOrder is an experimental quantity, while molecularity is a theoretical quantity.
  2. BOrder is applicable only to complex reactions, while molecularity applies to elementary reactions.
  3. COrder can be zero or a fraction, while molecularity cannot be zero or a non-integer.
  4. DOrder is determined by the rate-determining step, while molecularity is determined by the overall reaction rate.

Correct answer

C. Order can be zero or a fraction, while molecularity cannot be zero or a non-integer.

Step-by-step solution

The order of a reaction can be zero or a fraction, but molecularity cannot.
