So, here's how a rough sketch of a potential energy diagram would look like for this reaction. The difference between the energy level of the products and the energy level of the reactants is equal to the enthalpy change of reaction, #DeltaH_"rxn"#. Since the products are lower in energy, #DeltaH_"rxn"# carries a negative sign. 3.2.1 Energetics - Enthalpy change (ΔH) - A level chem On an enthalpy level diagram, higher positions will be less stable (with more internal energy) therefore, if the product is lower, heat is released (more stable, ΔH is -ve) but if it is higher, heat is gained (less stable, ΔH is +ve). Enthalpy level diagrams It is important to get the following facts clear in your mind:

Hess's Law and enthalpy change calculations Enthalpy change is simply a particular measure of energy change. You will remember that the enthalpy change is the heat evolved or absorbed during a reaction happening at constant pressure. I have labelled the vertical scale on this particular diagram as enthalpy rather than energy, because we are specifically thinking about enthalpy changes. 23 Consider the following enthalpy level diagram What is ... 23 consider the following enthalpy level diagram what. 23. Consider the following enthalpy level diagram. What is the standard enthalpy change of the following reaction?
