Скачать или смотреть Thermodynamics: Partial Molar Volume of a Binary Mixture

A walk through of an example problem finding an expression for the partial molar volume of a species in a binary mixture:

For a given binary system at constant T and P, the molar volume (in cm3/mol) is given by
Vm = 100ya + 70yb + 3yayb
(a) What is the pure species molar volume for species a, Vm,a?
(b) Come up with an expression for the partial molar volume, V ̅a, in terms of yb. What is the partial molar volume at infinite dilution, V ̅a∞ ?
(c) Is the volume change of mixing, ΔVm,mix , greater than, equal to, or less than 0? Explain.
