Abstract: This chapter explores thermochemistry, one of the principal applications of thermodynamics to chemistry. It begins by looking at how the strengths of bond are expressed in terms of the bond dissociation enthalpy and their mean values over a series of related compounds. The chapter then considers the standard enthalpy of combustion, which is the change in standard enthalpy per mole of combustible substance. Meanwhile, the reaction enthalpy is the change in enthalpy that accompanies a chemical reaction. The standard reaction enthalpy (the ‘standard enthalpy of reaction’) is the value of the reaction enthalpy when all the reactants and products are in their standard states. The chapter also discusses Hess's law, the standard enthalpy of formation, exothermic and endothermic compounds, and Kirchhoff's law.
