WebSep 24, 2024 · The bimolecular nucleophilic substitution reaction follows second-order kinetics; that is, the rate of the reaction depends on the concentration of two first-order reactants. In the case of bimolecular nucleophilic substitution, these two reactants are the haloalkane and the nucleophile. WebThis can be explained considering that the reaction occurs in 2 steps: NO + Br2 ----> NOBr2 ( The first reaction is the slow step, therefore it dictates the rate) NOBr2 + NO -----> 2NOBr ----------------------------------------- 2NO + Br2 ----> 2NOBr ( The sum of the 2 reactions above gives the original reaction) Comment ( 5 votes) Upvote Downvote
