WebJan 10, 2024 · If delta H is positive, the reaction is endothermic, because the system is absorbing heat. If delta H is negative, it will be exothermic, because the system is releasing heat. Also, endothermic reactions favor product formation, while exothermic reactions favor reactant formation.
