For any highly complex multi-step chemical reaction, the defining term "Overall Molecularity" of the — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

Molecularity strictly defines the literal number of distinct molecules colliding simultaneously in a single, isolated elementary step. Because a complex reaction operates through a staggered series of vastly different sequential elementary steps, applying a single, unified "overall molecularity" to the entire macroscopic process is physically absurd and entirely undefined.
