Molecularity - Wikipedia

WebAn elementary reaction is a reaction that occurs in a single step. The rate law for an elementary reaction can be derived from the coefficients of the reactants in the balanced equation. ... We can classify this reaction according to its molecularity, which refers to the number of participating molecules. So if we think about one molecule of A ... 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.
