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

Regarding to Henry's law which of the following is not correct statement?
  1. Different gases have different $K_H$ (Henry's law constant) values at the same temperature
  2. The partial pressure of the gas in vapour phase is proportional to the mole fraction of the gas in the solution
  3. Higher the value of $\mathrm{K}_{\mathrm{H}}$ at a given pressure, higher is the solubility of the gas in the liquids
  4. The value of $K_H$ increases with increase of temperature and $K_H$ is function of the nature of the gas

Solution

$\mathrm{p}=\mathrm{K}_{\mathrm{H}} \times \mathrm{x}$ 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.
