Abstract
This paper is concerned with the dielectric relaxation times (τ) and the dipole moments (μ) of the binary mixtures of different molar concentrations of acetonitrile (CH3CN) in the binary mixtures of N-Methylacetamide (NMA) and acetonitrile (CH3CN) in benzene solutions. The physical parameters τ and μ have been calculated by using standard standing wave microwave techniques and Gopala Krishna’s single frequency (9.90 GHz) concentration variational method at different temperatures (25 °C, 30 °C, 35 °C, 40 °C). The dielectric relaxation process have been found to be an activated process. The energy parameters (ΔH, ΔF, ΔS) for the dielectric relaxation process of binary mixtures containing 30% mole-fraction of CH3CN have been calculated at the respective given temperatures and a comparison has been made with the corresponding energy parameters (ΔHη, ΔFη, ΔSη) 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. Solute–solute and solute–solvent molecular associations have been predicted.
