WebHenry's constant is finite on the path along the vapor-pressure curve of the solvent. At the critical point, a finite limit is reached [58,59]. The initial slope of the critical line starting at the critical point characterizes the phase behavior near the critical point. WebJul 19, 2024 · Henry's Law Henry’s law states that the concentration of a dissolved gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. C g = k P g Here, Cg is the concentration of the dissolved gas (in mol L –1 ), k is Henry’s constant (specific to the gas), and Pg is the partial pressure of the gas.
