Molecular Associations in Binary Mixture of Pyridine and Nitrobenzene in Benzene Solution using Microwave Absorption Data
-
Abstract
The dielectric relaxation time (τ) of binary mixtures of different molar concentrations of pyridine (C5H5N) and nitrobenzene (C6H5NO2) in benzene solution has been calculated by using standard microwave techniques and Gopala Krishna’s single frequency (9.875 GHz) concentration variational method at different temperatures (25, 30, 35 and 40 °C). It is found that the dielectric relaxation time (τ) varies non-linearly with the increasing molar concentration of pyridine in the binary mixture of pyridine and nitrobenzene. Dielectric relaxation has been found to be an activated process. Energy parameters (ΔHε, ΔFε, ΔSε) for this activated process have been calculated and compared with the parameters (ΔHη, ΔFη, ΔSη) of viscous flow process. Based upon above results solute–solvent and solute–solute molecular associations have been proposed.
