1. consider an napl mixture of tetrachloroethene (pce) and fuel containing btex (benzene, toluene, ethylbenzene, and xylene) with the following fractions: pce=0.10, b=0.15, t=0.15, e=0.08, and x=0.10. the vapor pressure (in atmosphere at 25°c) of the pure compounds are pce= 0.0251, b=0.126, t=0.0380, e=0.0126, and x=0.0117, and henry’s constant kh (in atm-l/mol at 25°c) for pce is 26.9. (a) assume paoult’s and henry’s laws apply, estimate the aqueous concentration of pce in water that is in equilibrium with this napl mixture. (b) estimate the reduction in aqueous pce concentration (solubility) due to the presence of betx. hint: first estimate the solubility when pce is the sole napl (mole fraction =1.0)
