NAPL mixture rachloroethene (PCE) and fuel containing BTEX?
Consider an NAPL mixture of tetrachloroethene (PCE) and fuel containing BTEX (benzene , touene, ethylbenzene,and xylene) with the following mole fractions : PCE 0.10 , B=).15 , T=0.15 , E=0.08 ,and X=0.10 . the vapor pressures 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)Assuming raoult’s and Henry’s law 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 BTEX.
