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
1.42900.LN/A 
1.53200.QN/AOnly the tabulated data between T = 273. K and T = 303. K from missing citation was used to derive kH and -Δ 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 α from missing citation were assumed to be identical.
1.23100.CN/A 
1.23200.CN/A 
1.23100.TN/A 
1.23100.QN/A missing citation refer to several references in their list of Henry's law constants but they don't assign them to specific species.
1.33100.N/AN/A 
1.23200.XN/AThe value is taken from the compilation of solubilities by W. Asman (unpublished).
1.2 XN/AValue given here as quoted by missing citation.
1.2 CN/A 
1.32800.XN/A 
1.23000.LN/A 
1.42800.LN/A 
1.23100.XN/AThe value is taken from the compilation of solubilities by W. Asman (unpublished).
1.1 cN/A 
1.23100.cN/A 
1.23200.XN/AThe value is taken from the compilation of solubilities by W. Asman (unpublished).
