Question

Regarding to Henry's law which of the following is not correct statement ?

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

Answer 1

Answer: (C)

$p=K_{H}\times x$
Where $K_{H}=$ Henry law constant
Henry's constant increases with increase in temperature while it decreases with increase in solubility. Hence, value of $K_{H}$
increases as solubility of gas increases is a wrong statement.
