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.

Options:

Answer:

Solution:

On increasing temperature, the given endothermic reaction becomes spontaneous. $Δ G = Δ H - T Δ S$ For spontaneity, $Δ G < 0$ Given, $Δ H > 0$ So, $Δ S$ should be +ve.
