Order and Molecularity of reaction - BYJUS

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 • Cage effect See more A termolecular (or trimolecular) reaction in solutions or gas mixtures involves three reactants simultaneously colliding, with appropriate orientation and sufficient energy. However … See more 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.

WebJan 11, 2014 · Molecularity, as per the collision theory, is defined only for elementary reactions. One of the things that define an elementary reaction is the fact that the entire transformation from reactants to products occurs simultaneously, and follows from a properly oriented, appropriately energetic collision of the reactant species. WebElementary bimolecular reactions that involve two molecules interacting to form one or more products follow second order rate kinetics. An example would be the following reaction between a nitrate molecule and carbon monoxide to form nitrogen dioxide and carbon dioxide: (9.3.3) N O 3 + C O N O 2 + C O 2
