Step-by-step explanation:
Enthalpy is the thermal energy involved in a chemical reaction or process. Carrying out the calculation of the enthalpy variation allows us to identify whether the reaction is endothermic or exothermic. If the result is negative, the reaction will be exothermic; if the result is positive, the reaction will be endothermic.
∆H = HP - HR
In this case, the products' enthalpy is higher than the reactants' enthalpy. It means that the enthalpy will be positive and the reaction is endothermic.
