Information

Gaseuous substance dissolition in liquid (Henry's law, Raoult's law, Nernst dissolution in one).

K_H =x_L / x_g	Henry's coefficient, Raoult's coefficient
Δ_solG = Δ_fG_L- Δ_fG_g= Δ_solH - T·Δ_solS = -R·T·log(K_H· (f_L / f_g))	molar Gibb's energy of the dissolition
Δ_solH = Δ_fH_L- Δ_fH_g	molar enthalpy of the dissolition
Δ_solS = Δ_fS_L - Δ_fS_g = k·log(Δ_solω)	molar entropy of the dissolition

x_L	mole fraction of the substance in the liquid
x_g	mole fraction of the substance in the gas
f_L	activity coefficient of the substance in the liquid
f_g	activity coefficient of the substance in the gas
Δ_fH_L	molar enthalpy of formation of the substance in the liquid
Δ_fH_g	molar enthalpy of formation of the substance in the gas
Δ_fS_L	molar entropy of formation of the substance in the liquid
Δ_fS_g	molar entropy of formation of the substance in the gas
Δ_solG	molar Gibbs energy of dissolvation of the substance in the liquid
Δ_solω	change of number of microstates of particles by dissolution
