Stoichiometry
Raoult's law states that 'the equilibrium vapor pressure that is exerted by a component in a solution is proportional to the mole fraction of that component'. This generalisation is based on the assumption that the

All of these
Component molecules are non-polar and no chemical combination or molecular association between unlike molecules takes place in the formation of the solution
Sizes of the component molecules are approximately equal
Attractive forces between like and unlike molecules are approximately equal

Stoichiometry
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.

No component is concentrated at the surface of the solution
In the formation of solution, chemical combination/molecular association between unlike molecules takes place
The component molecules are non polar and are of almost equal size
The attractive forces between like and unlike molecules are almost equal
