A) Exothermic and decreasing disorder
B) Endothermic and increasing disorder
C) Exothermic and increasing disorder
D) Endothermic and decreasing disorder
Correct Answer: B
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 \[\Delta S=+\,ve\] For\[\Delta H=-ve,\] reaction Should be exothermic and \[\Delta S=+ve\]for increase in disorder.You need to login to perform this action.
