Q25 / 180 · KCET 2021 · Chemistry

Choose the correct statement.

  • A
    $K_{\mathrm{H}}$ value is same for a gas in any solution.
  • B
    Higher the $K_{\mathrm{H}}$ value more the solubility of gas.
  • Correct answer
    C
    $K_{\mathrm{H}}$ value increases on increasing the temperature of the solution.
  • D
    Easily liquefiable gases usually has lesser $K_{\mathrm{H}}$ values.

Solution

Among the given statements only (c) statement is correct about the Henry's law constant. Other statement are incorrect because (a) $K_{\mathrm{H}}$ is a function of the nature of the gas and solvent used, thus $K_{\mathrm{H}}$ value is not same for a gas in any solution. (b) Higher the $K_{\mathrm{H}}$ value, less the solubility of the gas. (d) Easily liquefiable gases usually have higher $K_{\mathrm{H}}$ values.

Hence, the correct answer is option: 'C'.
