Vedclass · Answer

(C) For the formation of an ideal solution,the process is spontaneous,which implies $\Delta G According to the definition of an ideal solution:$\Delta H_{	ext{mix}} = 0$$\Delta V_{	ext{mix}} = 0$Since $\Delta H_{	ext{mix}} = 0$,there is no heat exchange between the system and the surroundings,so $\Delta S_{	ext{surroundings}} = 0$.Mixing increases the randomness of the components,so $\Delta S_{	ext{system}} > 0$.Using the Gibbs free energy equation: $\Delta G = \Delta H - T\Delta S$.Since $\Delta H = 0$ and $\Delta S > 0$,we get $\Delta G = -T\Delta S$,which is less than $0$ (negative).
