ChemistrySolutionsMHT CETMHT CET 2021 (24 Sep Shift 1)
Options:
  • 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 $\mathrm{K}_{\mathrm{H}}$ 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

The correct answer is: Higher the value of $\mathrm{K}_{\mathrm{H}}$ at a given pressure, higher is the solubility of the gas in the liquids
$$
\mathrm{p}=\mathrm{K}_{\mathrm{H}} \times \mathrm{x}
$$

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.
