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 |
|---|---|---|---|---|
| 210. | Q | N/A | missing citation give several references for the Henry's law constants but don't assign them to specific species. Value at T = 303. K. | |
| 2.1 | 7400. | M | N/A | The data from Table 1 by missing citation was used to redo the regression analysis. The data for acetone in their Table 2 is wrong. |
