ABSTRACT

In the present study, we report experimental densities oqP and viscosities ogP of aqueous solutions of nicotinic acid and nicotinamide within the concentration range (0 to 0.1) mol kg 1 at T = (275.15, 277.15 and 279.15) K. These parameters are then used to obtain thermodynamic and transport functions such as apparent molar volume of solute oV/P, limiting apparent molar volume of solute oV0 /P, limiting apparent molar expansivity of solute oE0 /P, coefficient of thermal expansion oa P, Jones Dole equation viscosity A, B and D coefficients, temperature derivative of B coefficient i.e. (dB/dT) and hydration number onHP, etc. The activation parameters of viscous flow for the binary mixtures have been determined and discussed in terms of Eyring s transition state theory. These significant parameters are helpful to study the structure promoting or destroying tendency of solute and various interactions present in (nicotinic acid + water) and (nicotinamide + water) binary mixtures.
