Under standard state conditions, the free energy formula can be rewritten with the
equilibrium constant replacing AG° as follows: - RT In Keq = AH0 - TAS°
Therefore, the level of solubility is related to the change in enthalpy (or heat
content) ...

and enthalpy conditions. For example, at 25° C, water is soluble at 0.275 mole
fraction in 1-octanol, while 1-octanol is only soluble at 7.5 X 10"5 mole fraction in
water (Sangster, 1997). Without a full examination of hydrophobic effects, these ...

Like partitioning itself, the temperature effect on partitioning is a function of
entropy and enthalpy realized in a system. Free energy from entropy is a direct
function of temperature (TAS), however temperature can also impact enthalpy.
