Abstract  

Variation of activation energy for tracer-diffusion of Co2+ ions in Ni(NO3)2, Co(NO3)2 and Mn(NO3)2 is investigated using 1% agar gel over the temperature range of 25 to 45 °C. The activation energies are obtained by the least square fitting of the diffusion coefficient data obtained at various temperatures through the Arrhenius plots. Further, the extent of obstruction effect by gel macromolecules for Co2+ ions in Ni(NO3)2, Co(NO3)2 and Mn(NO3)2 systems at various concentrations of the electrolyte have been determined. The decrease in activation energy is explained by considering the changes in the physical properties of the solution with concentration at microscopic level, while the decrease in obstruction effect expressed in terms of a is accounted for on the basis of competitive hydration between ions and agar molecule.
