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