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)

H (mol/kg*bar) d(ln(kH))/d(1/T) (K) Method Reference Comment
0.00141600.LN/AThe parameterization given by missing citation (parameters A, B, C) doesn't fit the data in the same paper for this substance. Therefore the parameteriztaion of the solubility data (X1) was recalculated.
0.00131900.QN/AOnly 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.
0.0015 QN/A missing citation give several references for the Henry's law constants but don't assign them to specific species.
