During the decomposition of an oxide into oxygen and metal vapour entropy increases as gas is produced in the reaction.

Decomposition of an oxide is an endothermic change. This is because it is reverse of combustion reaction and all combustion reactions are exothermic in nature.

Since both

Δ H

and

Δ S

are positive, the temperature should be high enough so that

T Δ S > Δ H

Thus, all are correct answers.
