Exergy organic chemicals

The objective of this work is to develop a set of group contributions for estimating the specific chemical enthalpy, 8, and the specific chemical exergy, e, which are essential in carrying out the thermodynamic analysis and synthesis of a process system. This set of group contributions can be employed not only for known organic compounds, but also for new organic compounds which are yet to be synthesized or discovered. 

Usually, r]e< 1, but sometimes values of Tje> 1 can appear if the restorable natural resources are used for the process. The transition from one form of exergy to another, for example, from chemical to structural, may create economic value. Self-organization is a production process, and exergy is necessary to build a structure with a value, that may not be measured and described by exergy.
