Question

Dissolution of ammonium chloride in water is an endothermic reaction, yet it is a spontaneous process. This is due to the fact that

• A. $\Delta His + ve,\Delta Sis - ve$
• B. $\Delta His - ve,\Delta Sis + ve$
• C. $\Delta His + ve,\Delta Sis + veand\Delta H < T\Delta S$
• D. $\Delta His + veand\Delta H > T\Delta S$

Answer 1

Answer: (C)

$\Delta His + ve,\Delta Sis + veand\Delta H < T\Delta S$

Answer 2

: $\Delta G$will be negative under these conditions.
