Difference Between Order of Reaction and Molecularity

WebThe molecularity of an elementary reaction is the number of reactant species involved, typically one (unimolecular), two (bimolecular), or, less commonly, three (termolecular). The overall rate of a reaction is determined by the rate of the slowest in its mechanism, called the rate-determining step. ... In chemistry, molecularity is the number of molecules that come together to react in an elementary (single-step) reaction and is equal to the sum of stoichiometric coefficients of reactants in the elementary reaction with effective collision (sufficient energy) and correct orientation. Depending on how … See more In a bimolecular reaction, two molecules collide and exchange energy, atoms or groups of atoms. This can be described by the equation which corresponds to the second order rate law: See more • Reaction rate • Dissociation (chemistry) • Lindemann mechanism • Crossed molecular beam See more A termolecular (or trimolecular) reaction in solutions or gas mixtures involves three reactants simultaneously colliding, with appropriate … See more It is important to distinguish molecularity from order of reaction.
