WebThe dimensionless Henry’s law constant [air]/[water] for trichloroethylene (TCE) at 25°C is 0.4. A sealed glass vial is prepared that has an air volume of 4 mL overlying an aqueous volume of 36 mL. TCE is added to the aqueous phase so that initially it has an aqueous phase concentration of 100 ppb. After the system equilibrates, ... Web25 feb. 2015 · Henry’s law constant (HLC) represents the equilibrium partition coefficient of a volatile compound between air and water. It reflects the relative volatility of a particular compound and represents a major property to describe fate and transport modeling in environmental risk assessment [1, 2].
WebThe heat of desorption is about 15 kJ/mole. At 24°C, the nominal Henry's law constant was smaller than would have been obtained by extrapolating the values found at higher temperature. The diffusion constants increase with temperature from about 2 × 10 −13 to 3 × 10 −7 cm 2 /sec.
