Effect of KCl and CsCl electrolytes on the kinetics of reaction between bromopropionate and thiosulphate ions

ABSTRACT

The primary salt effect on reaction between beta- bromo - propionate and thiosulphate ions has been studied in presence of various concentrations of potassium chloride and ceasium chloride at different temperatures. The effects of ionic strength on rate constants are very specific and dependent upon the ionic and the concentration of the cation of the added salt. The rate constants have been found to decrease with increasing concentrations of inert salts. The activation parameters such as energy of activation [E[a]] change in entropy of activation [delta S[++]],change in free energy of activation [delta G[++]] and temperature coefficients of the rate constants in the presence of potassium chloride and ceasium chloride have been evaluated as a function of ionic strength
