A) Exothermic and decreasing disorder
B) Endothermic and increasing disorder
C) Exothermic and increasing disorder
D) Endothermic and decreasing disorder
Correct Answer: C
Solution :
For a spontaneous reaction,\[\Delta G=-ve.\] From Gibbs -Helmholtz equation \[\Delta G=\Delta H-T\Delta S\] \[\Delta G=-ve\], when\[\Delta H=-ve\]and\[\Delta G=-ve\]. For\[\Delta H=-ve,\] reaction should be exothermic and \[\Delta S=+ve\] for increase in disorder.
