Let us consider an endothermic reaction which is non-spontaneous at the freezing point of water. However, the reaction is spontaneous at boiling point of water. Choose the correct option
✓ Correct answer: a)
Both ΔH and ΔS are (+ve)
Explanation
The given reaction is an endothermic process that is non-spontaneous at the freezing point of water but becomes spontaneous at the boiling point of water. This indicates that the process follows Gibbs free energy equation
\(\Delta G=\Delta H-T\Delta S\)
It is only possible when \(\Delta H\) and \(\Delta S\) both are positive.
