Why is the term molecularity not applicable for complex reactions ?

1.	Why is the term molecularity not applicable for complex reactions ?
Answer» Answer: A complex reaction proceeds through several ELEMENTARY reactions. Numbers of molecules INVOLVED in each elementary reaction MAY be different i.e., the molecularity of each step may be different. Therefore, discussion of molecularity of overall complex reaction is meaningless. On the other hand, order of a complex reaction is determined by the slowest step in its mechanism and is not meaningless even in the CASE of complex reactions.
