Density and viscosity values of valine at different concentrations (0.02, 0.04, 0.06, 0.08 and 0.1) M in aqueous paracetamol of concentration (0.025 - 0.1) M insteps of 0.025 M have been used to evaluate various important thermodynamic parameters like apparent molal volume, partial molal volume, the partial molal volume transfer, partial molal expansivity, isobaric thermal expansion coefficients, hydration number, viscosity B-coefficients, B-coefficient transfer, ratio of B-coefficient to partial molal volume, temperature derivative of B-coefficient, salvation number, free energy of activation of viscous flow per mole of solvent and per mole of solute and thermodynamic activation parameter of transfer from ground state to transition state. These thermodynamic parameters have been predicted in terms of solute-solute and solute-solvent interactions and structure making/breaking ability of solutes in the given solution. |
