Vedclass · Answer

(D) An ideal solution is defined by the following characteristics: $1$. $\Delta H_{mix} = 0$ (Enthalpy of mixing is zero). $2$. $\Delta V_{mix} = 0$ (Volume of mixing is zero). $3$. $\Delta U_{mix} = 0$ (Internal energy of mixing is zero). $4$. The solution obeys Raoult's law over the entire range of concentration,so $\Delta P = 0$. However,for any spontaneous mixing process,the entropy of mixing $\Delta S_{mix}$ is always positive. Since $\Delta G_{mix} = \Delta H_{mix} - T\Delta S_{mix}$,and $\Delta H_{mix} = 0$ while $\Delta S_{mix} > 0$,it follows that $\Delta G_{mix} = -T\Delta S_{mix} Therefore,the statement $\Delta G_{mix} = 0$ is incorrect.
