The standard enthalpy of formation is the change in enthalpy for a reaction producing one mole of a product in its standard state from its elements in their standard states. A table of standard enthalpies of formation can be found in your textbook and using these values in combination with Hess’s Law, we can calculate the standard enthalpy change for chemical reactions provided we know the standard enthalpy values for all of the products and reactants.

We can now calculate the amount of heat released or absorbed in a given chemical reaction by using the concepts from this chapter along with the stoichiometry of chemical reactions concepts from Chapter 3.
