82Br has been employed as a tracer to study Kinetics of first order reaction. The study was carried for different concentrations of KBr solution (electrolyte), different temperatures and for different amount of ion exchange resins. Reaction rates were calculated by using first order reaction rates equation from the reaction rates the energy of activation were calculated. The energy of activation was found to decrease with increase in concentration of the electrolyte. For concentration of 0.005 KBr solution energy of activation is found to be 6.801 KJ/mole which decreases to 6.120 KJ/mole for 0.1 M solution.
