The heat of formation can be either endothermic or exothermic, depending on the specific reaction and the compounds involved.
- **Exothermic reactions** occur when heat is released during the formation of a compound from its elements. In these cases, the heat of formation is negative, indicating that the products have lower energy than the reactants and the formation process releases energy.
- **Endothermic reactions** occur when heat is absorbed during the formation of a compound from its elements. In these cases, the heat of formation is positive, indicating that the products have higher energy than the reactants and the formation process requires energy input.
To summarize, the sign and nature of the heat of formation depend on the specific reaction and substances involved.
