A) \[\Delta {{S}_{(mix)}}=0;\,\Delta {{G}_{(mix)}}=0\]
B) \[\Delta {{H}_{(mix)}}=0;\,\Delta {{S}_{(mix)}}<0\]
C) \[\Delta {{V}_{(mix)}}=0;\,\Delta {{G}_{(mix)}}>0\]
D) \[\Delta {{S}_{(mix)}}=0;\,\Delta {{G}_{(mix)}}<0\]
Correct Answer: D
Solution :
: For an ideal solution; \[\Delta H=0\] and \[\Delta V=0\] From, \[\Delta G=\Delta H-T\Delta S\] \[\Delta G=-ve\] Hence, \[\Delta G<0\] and \[\Delta S>0\]
