Which one of the following statements regarding Henry's law is not correct?
- a
Different gases have different (Henry's law constant) values at the same temperature
- b
The partial pressure of the gas in vapour phase is proportional to the mole fraction of the gas in the solution
- c✓
Higher the value of at a given pressure, higher is the solubility of the gas in the liquids
- d
The value of increases with increase of temperature and is function of the nature of the gas
Higher the value of at a given pressure, higher is the solubility of the gas in the liquids
Strategy:\n> Recall the fundamental properties of Henry's Law (). Key points: depends on the gas nature and temperature, and it is inversely proportional to solubility at a constant pressure.\n\nStep 1: Evaluate Statement (3)\nThe statement says: "Higher the value of at a given pressure, higher is the solubility of the gas".\nFrom , if is large, then (solubility) must be small for the same pressure .\nThus, Statement (3) is incorrect.\n\nStep 2: Verify other statements\n- (1): Correct, is specific to the gas-solvent pair.\n- (2): Correct, is the definition of the law.\n- (4): Correct, increases with temperature (meaning gases leave the solution, i.e., solubility decreases).\n\n
