An aqueous solution is in . Which change will cause the vapour pressure of the solution to increase?

  1. A
    Addition of water
  2. B
    Addition of
  3. C
    Addition of
  4. D
    Addition of

Solution & Step-by-step Explanation

Vapour pressure of a solution decreases as the concentration of non-volatile solute increases (Relative Lowering of Vapour Pressure).To increase the vapour pressure, we need to decrease the mole fraction of the solute (dilute the solution).Addition of water (solvent) reduces the concentration of , thereby increasing the vapour pressure of the solution toward that of pure water.
