Abstract


The physicochemical parameters (density (ρ), viscosity (η), ultrasonic sound velocity (U), acoustical impendence (Z), isentropic compressibility (κs), intermolecular free path length (Lf), Rao's molar sound function (Rm), van der Waals constant (b), internal pressure (π), free volume (Vf) and viscous relaxation time (τ), solvation number (Sn) of binary mixture of 5-(4-nitrobenzylidene)-2-(thiophen-2-yl)-3-(4H-1,2,4-triazol-4-yl)thiazolidin- 4-one, (TZ1) and 5-(4-chlorobenzylidene)-2-(thiophen-2-yl)-3-(4H-1,2,4-triazol-4-yl) thiazolidin-4-one, (TZ2) in N,N-dimethyl formamide (DMF) and dimethyl sulfoxide (DMSO) were calculated at three temperatures viz. (298.15, 308.15 and 318.15) K at atmospheric pressure. Additionally, a comparison between experimental results of the binary mixture was studied to analyse how the change in polar aprotic solvent and the structural organisation make a change in the values of enthalpy of activation (ΔH*), Gibbs energy of activation (ΔG*) and entropy of activation (ΔS*).
