Choose the incorrect statement:

Options

  1. AHigher the K _ H value for a gas at a given pressure, higher is its solubility in that solvent.
  2. BK _ H value for a gas present in a given solvent depends on the nature of solute and solvent.
  3. CK _ H value changes with change in the partial pressure of the gas.
  4. DK _ H value is temperature dependent.

Correct answer

A. Higher the K _ H value for a gas at a given pressure, higher is its solubility in that solvent.

Step-by-step solution

By Henry's Law: p = K_H x , where x is the mole fraction (solubility) of gas. Rearranging: x = p K_H At a given pressure, solubility x is inversely proportional to K_H . Higher K_H lower solubility. (1) Incorrect: Higher K_H means lower solubility, not higher. (2) Correct: K_H depends on the nature of gas and solvent. (3) Correct: K_H is independent of partial pressure (it is a constant at given temperature). (4) Correct: K_H is temperature dependent. Incorrect statement: (1)
