Under what conditions can a non-spontaneous reaction be made spontaneous? when an endothermic reaction has a positive change in entropy and the temperature is greatly increased when an endothermic reaction has a positive change in entropy and the temperature is greatly decreased when an exothermic reaction has a positive change in entropy and the temperature is greatly increased when an exothermic reaction has a positive change in entropy and the temperature is greatly decreased when an exothermic reaction has a negative change in entropy and the temperature is greatly increased

For an endothermic reaction to occur, the change in entropy must be positive; on the other hand, the change in entropy must be negative for an exothermic reaction to occur. Moreover, the occurrence of endothermic reactions is favored when the temperature is increased, and the occurrence of exothermic reactions is favored when the temperature is reduced. Thus, the reaction may be made spontaneous when an endothermic reaction has a positive change in entropy and the temperature is greatly increased.
