Suppose you have a liquid in equilibrium with its gas phase inside a closed container that is in contact witha thermal reservoir. you then pump in an inert gas raising the pressure exerted on the liquid. does thefraction of the liquid in the vapor phase decrease or increase? a) use the definition of the gibbs free energy in terms of the chemical potential and the assumption that thevapor phase is an ideal gas to show that the chemical potential depends on the pressure in the following way: pμ(t, p) = μ(t, p 0) + kb t ln, p 0where p is the total pressure and p 0 is the initial vapor pressure in the absence of the added inert gas.
