ABSTRACT
Partial molar volumes (oo v ) and viscosity B-coefficients for nicotinamide in (0.00, 0.05, 0.10, 0.15, and 0.20) mol*dm.3 aqueous resorcinol solutions have been determined from solution density and viscosity measurements at (298.15, 308.15, and 318.15)K as a function of the concentration of nicotinamide (NA). Here the relation oo v = a0 + a1T + a2T 2, has been used to describe the temperature dependence of the partial molar volume oo v . These results and the results obtained in pure water were used to calculate the standard volumes of transfer oo v and viscosity B-coefficients of transfer of nicotinamide from water to aqueous resorcinol solutions to study various interactions in the ternary solutions. The partial molar volume (oo v ) and experimental slopes obtained from the Masson equation have been interpreted in terms of solute solvent and solute solute interactions, respectively. The viscosity data have been analyzed using the Jones Dole equation, and the derived parameters B and A have also been interpreted in terms of solute solvent and solute solute interactions, respectively, in the ternary solutions.The structure making or breaking ability of nicotinamide has been discussed in terms of the sign of (a2oo v /aT 2)P. The activation parameters of viscous flow for the ternary solutions studied were also calculated and explained by the application of transition state theory.
