A thermodynamic property of a mixture is given by 

a. Develop expressions for the partial molar properties θ̅₁, θ̅₂, and θ̅₃ as a function of the pure component molar properties, the mole fractions, and the parameters a₁₂, a₁₃, a₁₂, and a₁₂₃. 

b. Obtain expressions for the infinite-dilution value of θ̅₁ in solutions of varying concentrations of species 2 and 3. Repeat for θ̅₂ in mixed solvent solutions of 1 and 3, and for θ̅₃ in mixed solvent solutions of 1 and 2.
