Henrys Law Constants: methane to tetrachloromethane
Henry's Law constants for gas and organic compound solubility in water — solubility form H_cp [mol/L/atm], volatility form H_kH [atm·L/mol], dimensionless form H_cc, and van't Hoff temperature-dependence parameter d(lnH)/d(1/T) [K]; covers 148 compounds at 25°C reference in water; simple inorganic gases per Sander (2023) and CRC Handbook 97th Ed. Tables 5-134/5-135; organic and halogenated compounds per CRC Handbook 97th Ed. Table 5-139
