The standard enthalpy of formation ΔHf∘, is the standard enthalpy change for the formation reaction of a certain substance. This substance may be a single atom, an ion, or a chemical compound. The reactants are the constituent elements and all species in the e...
Standard Enthalpy of Reaction: The enthalpy of a reaction can be calculated by using the following equation: ΔHrxn∘=∑iviΔHio The equation above is a consequence of Hess' Law. The individual enthalpies of formation can be found on chemistry book...
