Question

Solubility of a gas X in liquid Y is given by Henry's law written as $P=K_H\times x$ . Where $K_H$ is Henry constant, P is partial pressure of the gas and x is mole fraction of gas in liquid. Which of the following is incorrect about $K_H–$

• A. It depends on nature of gas X
• B. It is independent of nature of liquid Y
• C. It is a function of Temperature
• D. It changes with change in partial pressure of gas.

Answer 1

The correct option is D It changes with change in partial pressure of gas.

Henry constant $K_H$ depends on nature of gas, solvent and temperature. But it does not change with partial pressure of the gas.
