Vedclass · Answer

(D) $(1)$ Ideal solutions obey Raoult's law over the entire range of temperature and concentration: This is true. An ideal solution is one in which the intermolecular interactions between the components are identical to those between the molecules of the individual components.$(2)$ For an ideal solution,$\Delta_{	ext{mix}}V = 0$: This is true. In an ideal solution,the volume change upon mixing is zero,meaning the total volume of the solution is the sum of the volumes of the individual components.$(3)$ Non-ideal solutions do not obey Raoult's law over the entire range of concentration: This is true. Non-ideal solutions exhibit deviations from Raoult's law due to differences in intermolecular forces between the components.$(4)$ The vapour pressure of a non-ideal solution always lies between the vapour pressures of the pure components: This statement is false. In non-ideal solutions,the vapour pressure can be higher (positive deviation) or lower (negative deviation) than the vapour pressures of the pure components.
