Pseudo first order reaction with example
WebA pseudo first order reaction is a reaction that is truly second order but can be approximated to be first order under special circumstances. For example, a second order reaction of the type A + B ... WebPseudo-first-order reactions are reactions that are not first-order but appear to be first-order due to larger concentrations of one or more reactants than the other reactants. Here pseudo means “fake”. The reaction is bimolecular but whose order is one. Example One example is acid-catalyzed hydrolysis of ethyl acetate.
