A solution containing components A and B follows Raoult's law if:

Options

  1. AA - B attraction force is greater than A - A and B - B
  2. BA - B attraction force is less than A-A and B-B .
  3. Cattraction force remains same as in A - A and B - B
  4. Dvolume of the solution is different from the sum of volume of the solute and the solvent.

Correct answer

C. attraction force remains same as in A - A and B - B

Step-by-step solution

Raoult's law is valid for ideal solution only. These two components A and B follows the condition of Raoult's law if the force of attraction between A and B is equal to the force of attraction between A-A and B-B Positive non-ideal behavior of the vapor pressure of a solution follows Henry's Law at low concentrations and Raoult's Law at high concentrations (pure).
