Chapter Objectives

• Explain the meaning of standard heat (enthalpy) of formation, heat (enthalpy) of reaction, and higher and lower heating values.

• List the standard conventions and reference states used for reactions associated with the standard heat of formation and the heat of combustion.

• Calculate the standard heat of reaction from tabulated standard heats of formation (or combustion) for a given reaction.

• Understand how to combine the heat of formation with sensible heat changes to solve problems involving chemical reactions. ...
