Data compiled by: Rolf Sander
Henry's Law constant (water solution)
kH(T) = k°H exp(d(ln(kH))/d(1/T) ((1/T) - 1/(298.15 K)))
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)
|k°H (mol/kg*bar)||d(ln(kH))/d(1/T) (K)||Method||Reference||Comment|
|0.00078||640.||Q||N/A||Only the tabulated data between T = 273. K and T = 303. K from missing citation was used to derive kH and -«DELTA» kH/R. Above T = 303. K the tabulated data could not be parameterized by equation (reference missing) very well. The partial pressure of water vapor (needed to convert some Henry's law constants) was calculated using the formula given by missing citation. The quantities A and «alpha» from missing citation were assumed to be identical.|
