Trimolecular reactions are uncommon because
WebThe order respect to a reactant does not necessarily correspond to the coefficients of the reaction, this because a reaction can occur in multiple elementary reactions. For example the reaction 2NO + Br2 ----> 2NOBr has the experimental rate law Rate = k {NO} {Br2} This can be explained considering that the reaction occurs in 2 steps: Web3.1.1.1: SN2 reactions. An elementary bimolecular reaction originates from a collision between two reactants. Whether or not a collision results in a chemical reaction is determined by the energy of the reactants and their orientation. The total energy of the two reactants must be in excess of the activation energy, E a, and the reactants must ...

WebA termolecular reaction involves three reacting molecules in one elementary step. Termolecular reactions are relatively rare because they involve the simultaneous collision of three molecules in the correct orientation, a rare event.
