0.4mg of PCE was spiked into a 12mL deionized water in a 20mL vial.
After about 10 hours, it was assumed that equilibration between gas and liquid phases was achieved.
Calculate PCE concentrations(mg/L) in gas and liquid phases, respectively.
Use the equation below to obtain Henry`s constant.
Use a dimensionless Henry`s constant and assume the temperature of the system is 20`C
(Hint: Need to conduct mass balance on PCE)
H=exp(12.5-4.921000/293.2) (atm.m3/mol)
H=exp(12.5-4.921000/293.2)=0.0138 atm.m3/molH`=H/RT(R:기체상수,8.2510-5293.2) =(0.0138)/(8.2510-5293.2) =0.571(무차원헨리상
