प्रश्न
Assertion (A): Order of reaction is applicable to elementary as well as complex reactions.
Reason (R): For a complex reaction, molecularity has no meaning.

उत्तर
Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
Explanation:
The order of reaction applies to both simple and complex reactions. A complicated reaction is composed of numerous elementary reactions. The number of molecules participating in each elementary reaction may differ, implying that the molecularity of each step may differ. As a result, discussing the molecularity of the total complex reaction is pointless.
