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