The reaction shows first order dependence each on [BAB], [m-HBA] and catalyst [Ru(III)]. During the reaction, it is observed that there is an inverse first order with respect to [H+]. The rate remained unchanged with the variation in the ionic strength of the medium for [m-HBA]. The addition of benzene sulphonamide [BSA], which is one of the reaction products, had no significant effect on the reaction rate. Thermodynamic parameters were computed by studying the reaction at different temperatures (303&plusmn;318K). The rate laws derived are in excellent agreement with the experimental results. A suitable mechanism has been proposed.<br /> <em>Key words :</em> m-hydroxy benzoic acid, N-Bromobenzene sulphonamide, Ru(IIl), Perchloric acid, Kinetics and Mechanism.</p> https://journalofchemistry.org/paper/811/ Kinetics and Mechanism Perchloric acid
