The type of reaction shown by the equation is Endothermic.
The given reaction involves the absorption of energy
, which indicates an endothermic process.
In an endothermic reaction, the system absorbs heat from its surroundings, leading to an increase in the internal energy of the system. The positive value of the enthalpy change
indicates that energy is being taken in during the reaction.
If the enthalpy change had carried a negative sign instead of a positive one, the reaction would have been exothermic instead of endothermic. In exothermic reactions, energy is given off to the surrounding instead of being absorbed.
