Unformatted text preview: Chapter 6 Thermochemistry of multiple reactions See Turns, Chapter 4, 5, 6 See Kuo, Chapters 1, 2 See Kondepudi and Prigogine, Chapter 16, 19 This chapter will extend notions associated with the thermodynamics of a single chemical reactions to systems in which many reactions occur simultaneously. 6.1 Summary of multiple reaction extensions Consider now the reaction of N species, composed of L elements, in J reactions. This section will focus on the most common case in which J ≥ ( N − L ), which is usually the case in large chemical kinetic systems in use in engineering models. While much of the analysis will only require J > 0, certain results will depend on J ≥ ( N − L ). It is not difficult to study the complementary case where 0 < J < ( N − L ). The molecular mass of species i is still given by M i = L summationdisplay l =1 M l φ li , i = 1 ,...,N. (6.1) However, each reaction has a stoichiometric coefficient. The j th reaction can be summarized in the following ways: N summationdisplay...
