Options:
A) Exothermic and decreasing disorder
B) Endothermic and increasing disorder

D) Endothermic and decreasing disorder
Show Answer
Answer:
Correct Answer: C
Solution:
$ \Delta G=\Delta H-T\Delta S $ for spontaneous process $ \Delta G $ should be negative in option (3) $ \Delta H=-ve\ and\ \Delta S=+ve $ than $ \Delta G=(-ve)-T(+ve) $
$ =-,ve $
