Question

Which one of the following statements regarding Henry's law not correct ?

• A. The value of $K_H$ increases with function of the nature of the gas
• B. Higher the value of $K_H$ at a given pressure, higher is the solubility of the gas in the liquids.
• C. The partial of the gas in vapour phase is proportional to the mole fraction of the gas in the solution.
• D. Different gases have different $K_H$ (Henry's law constant) values at the same temperature.

Answer 1

Answer: (B)

Higher the value of $K_H$ at a given pressure, higher is the solubility of the gas in the liquids.

Answer 2

Liquid solution
${P_{gas} = K_{H } \times X_{gas}}$
More is $K_H$ less is solubility, lesser solubility is at higher temperature. So more is temperature
more is $K_H$.
