[ Durig J.R., 1980, Durig J.R., 1980, 2, Durig J.R., 1981] for alkenes are different from experimental ones and given in TRC Tables [ Thermodynamics Research Center, 1997] by 3-5 J/mol*K. So the accuracy of their data could exceed 2 J/mol*K.

Henry's Law constant (water solution)

kH(T) = H exp(d(ln(kH))/d(1/T) ((1/T) - 1/(298.15 K)))
H = Henry's law constant for solubility in water at 298.15 K (mol/(kg*bar))
d(ln(kH))/d(1/T) = Temperature dependence constant (K)
