Question

This problem is (12.25) from a book  "Thermodynamics and Statistical Mechanics An Integrated Approach by M. Scott Shell"

12.25. A mixture containing species 1 with a dilute amount of species 2 is found to obey
Raoult's law, yP1
Dvap
x1Pi
', near xA
1 but not at other compositions. Show that
the solution then also obeys Henry's law for species 2 whenever it obeys Raoult's
law for species 1, with the former being given by
У»Р2 3D К х2
where Henry's constant K depends on temperature and pressure but not on
composition. That is, show that Raoult's law and Henry's law imply each other.
