Reaction molecularity
WebIn other words, the molecularity of an elementary reaction is defined as the number of reactant molecules taking part in the reaction. The Molecularity of a reaction is a theoretical concept. The Molecularity of a reaction can never be zero. The molecularity of this reaction is 2 because there are two reactant molecules in this reaction. 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. The order of reaction is an empirical quantity determined by experiment from the rate law of the reaction. … See more
