The estimation of heat of reaction is of great importance for the starting-up and scaling-up of chemical processes. At the first steps of the study of a process, the knowledge of its order of magnitude can be considered sufficient enough, so that for its estimation it is not necessary to call for complex techniques. Our purpose in this paper is to provide basic experimental and theoretical tools, in order to determine heats of reaction and other termodynamic quantities, such as heat of formation. For this scope, a general scanning is performed, starting from fundamental thermodynamic concepts to contribution additivity methods, such as Benson's method, in order to show their application in the frame of chemical process engineering.
