And molecularity is not even defined except for elementary reactions, so there is no question of molecularity for multi-step processes. – S R Maiti Jul 22, 2024 at 3:05 1 There is always one step that will be the slowest even if the difference is miniscule. By definition there can only be one slowest step.

The molecularity of an elementary reaction is the number of reactant particles (atoms, molecules, free radicals, or ions) that are involved in each individual … It is important to distinguish molecularity from order of reaction. The order of reaction is an empirical quantity determined by experiment from the rate law of the reaction. It is the sum of the exponents in the rate law equation. Molecularity, on the other hand, is deduced from the mechanism of an elementary reaction, and is used only in context of an elementary reaction. It is the number of molecules taking part in this reaction. cost of lunch in burj al arab
