Consider the system introduced in example 3.B.2 (p. 97) in which a 2 L sealed jar, half filled with water and half filled with air, contains 10^-3 mol of toluene. The equilibrium partitioning is described by Henry's law, so that the aqueous phase contains 0.78 x 10^-3 mol and the gas phase contains 0.22 x 10^-3 mol. To this system 150 mg of activated carbon is added to absorb toluene. Toluene partitioning between the sorbed and aqueous phases is described by the Freundlich isotherm qsube = 100Csube^0.45 (see example 3.B.5, p. 103 for clearer notation of this equation), where Csube is the aqueous concentration in mg/L and qsube is the sorbed mass concentration in mg toluene per g activated carbon. What is the new equilibrium concentration of toluene in water?
