Question 2

In which situation does a change in the volume of one phase by a factor 10 have little influence on

the resulting equilibrium concentrations of i in phase 1 or 2 of a two phase system.

the resulting mass distribution of i in phase 1 or 2 of a two phase system.

Answer: If the volume of a phase that originally contained less than 1% of the total compound in the system is changed by a factor 10 in either direction then the new equilibrium concentration will change very little while the mass fraction in this phase will change roughly proportional to the change in volume.
