WebHenry's Law 1 states that: At constant temperature, the concentration of a gas in solution is proportional to the partial pressure of the gas above the solution. Henry's Law can be written as a relationship: c ∝ P. where. c = concentration of gas in solution 2. P = partial pressure in the gas phase 3. WebAnswer: At constant temperature, the solubility of gas (S) varies inversely with Henry’s law constant. Thus, higher value of Henry’s law constant (K H), the lower is the solubility of a gas in the liquid. Question 2.Why Henry’s law is not applicable to CO 2 and NH 3?
