Question
Consider the following statements about Henry’s law
I. Mole fraction of a gas in a solution is proportional to the partial pressure of the gas over the solution.
II. Higher the value of KH at a given pressure, the lower is the solubility of the gas in the liquid.
III. Aquatic animals are more comfortable in hot water than in cold water.
The correct statement(s) among the following is/are:
[0.77 Mark]

Solution
The correct option is B I and II only
KH value increases with increase of temperature indicating that the solubility of gases increases with decrease of temperature. It is due to this reason that aquatic animals are more comfortable in cold water rather than in warm water because in cold water the amount of dissolved oxygen in higher.
