Question
When enthalpy (ΔH) is positive, the reaction is… Group of answer choicesexothermicendothermic
Solution
When the enthalpy change (ΔH) is positive, the reaction is endothermic. This is because a positive ΔH value indicates that energy is being absorbed from the surroundings, which is characteristic of an endothermic reaction. In contrast, an exothermic reaction releases energy to the surroundings, which would be indicated by a negative ΔH value.
