Abstract: The dielectric relaxation times() and the dipole moments() of the binary mixtures of different molar concentrations of acetone(CH3COCH3) in the binary mixtures of acetone and N-methylacetamide(NMA) in benzene solutions have been calculated by using standard standing wave microwave techniques and Gopala Krishna’s single frequency(9.88GHz) concentration variational method at different temperatures (25, 30, 35, 40°C).The dielectric relaxation process has been found to be an activated process. The energy parameters (H, F, S) for the dielectric relaxation process of binary mixtures containing 30% mole-fraction of acetone have been calculated at the respective given temperatures and the comparison has been made with the corresponding energy parameters (H, F, S) for the viscous flow. On the basis of the observations, it is found that the dielectric relaxation process can be treated as the rate process like the viscous flow process. The solute-solute and solute-solvent molecular associations have been predicted.
