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

Options

  1. AThe value of K H changes with the nature of the gas.
  2. BHigher the value of K H at a given pressure, higher is the solubility of the gas in the liquids
  3. CThe partial pressure of the gas in vapour phase is proportional to the mole fraction of the gas in the solutio
  4. DDifferent gases have different K H (Henry's law constant) value at the same temperature.

Correct answer

B. Higher the value of K H at a given pressure, higher is the solubility of the gas in the liquids

Step-by-step solution

Liquid solution P g a s = K H × X g a s a s K H ∝ 1 X g a s So, more is K H less is solubility. Solubility of gases is less at higher temperature. So more is the temperature more is the K H as K H ∝ 1 solubility ∝ temperature
