According to Raoult's law, "The vapor pressure exerted by component in a solution is proportional to the mole fraction of that component." Raoult's law is not applicable under the following assumption/condition?
Correct answer: B. In the formation of solution, chemical combination/molecular association between unlike
- A. No component is concentrated at the surface of the solution
- B. In the formation of solution, chemical combination/molecular association between unlike
- C. The component molecules are non polar and are of almost equal size
- D. molecules takes place
- E. The attractive forces between like and unlike molecules are almost equal
Explanation
Raoult's law works best when unlike molecules interact nearly as strongly as like molecules and no association or chemical reaction occurs. Molecular association between unlike molecules causes a major deviation from the law.
