3.4 CONCLUDING EXAMPLE
Select five substances from Table 3.5 that range in their values of vapor pressure,
aqueous solubility, and log K OW.
Calculate K AW as
vapor pressure (Pa)
solubility (g/m 3 ---------------------------------------------
)
where R is 8.314 Pa m 3 /mol K, and T is absolute temperature (298 K).
Calculate how 100 kg of each of these chemicals would partition at equilibrium
between three phases namely,
1 m 3 octanol (representing perhaps 100 m 3 of soil)
5000 m 3 water
10 6 m 3 air
( molar mass (g/mol )
-------------------------------------------------
R T
Calculate all the concentrations and amounts (which should add to 100 kg!) and
discuss briefly how each substance is behaving, i.e., its partitioning preference.
