Which one of the following statements regarding Henry's law is not correct? (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) The value of K_H increases with increase of temperature and K_H is a function of the nature of the gas. (4) Higher the value of K_H at a given pressure, higher is the solubility of the gas in the liquids.

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. The value of K_H increases with increase of temperature and K_H is a function of the nature of the gas.
4. Higher the value of K_H at a given pressure, higher is the solubility of the gas in the liquids.

Correct answer: Different gases have different K_H (Henry's law constant) values at the same temperature.

Solution

This statement is correct because Henry's law constant (K_H) varies for different gases due to their unique physical and chemical properties, which affect how they dissolve in a solvent at a given temperature.
