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 The attractive forces between like and unlike molecules are almost equal 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 No component is concentrated at the surface of the solution In the formation of solution, chemical combination/molecular association between unlike molecules takes place ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry In case of a solution (not of a solid in a liquid), whose total volume is less than the sum of the volumes of its components in their pure states, solubility is Increases with rise in pressure Increased with decrease in pressure Unchanged with pressure changes Independent of temperature Increases with rise in pressure Increased with decrease in pressure Unchanged with pressure changes Independent of temperature ANSWER DOWNLOAD EXAMIANS APP
