Solution

Correct Answer:

P = xA P°A + xB P°B

  1. Raoult's Law: For a solution of volatile liquids, the partial vapor pressure of each component () is directly proportional to its mole fraction () in the solution.
  2. Component A: , where is the vapor pressure of pure A.
  3. Component B: , where is the vapor pressure of pure B.
  4. Dalton's Law: The total pressure () above the solution is the sum of the partial pressures: .
  5. Significance: Ideal solutions strictly follow this relationship across the entire range of concentrations.
