Abstract:
Studies on the reaction rate between sodium monochloroacetate and sodium thiosulphate at 25' and at various concentrations of the reacting ions and various dielectric constant ? with acetone-water mixtures showed that the specific rate constant (k) increased with the dielectric constant. A comparison of the experimental values of the radii of the transient species for single sphere and double sphere models r≠. and rAB ) respectively (obtained from the linear plots of log ko and 1/?) with the theoretical values led to the conclusion that the transient species could best be described by the "SINGLE SPHERE" model for the reaction under consideration. Electrostatic and non-electrostatic contributions to the changes in the free energy of activation (Gand ?G ≠n.e.s ) in the formation of transient species were also evaluated.
