Abstract
This chapter is a survey of chemical reaction engineering basics: chemical species, reaction rates, representations of chemical reactions, chemical stoichiometry, thermodynamics, energy regularity for biotransformations, multiple reactions, conversion, yield, selectivity and yield factor, mass and energy balances, ideal chemical reactors, and economics of reaction engineering. Basic concepts are introduced, for example, elementary reaction, approximate reaction, coupled reaction, concentrations, specific reaction rate, Roels formula, transitional state, activation energy, chemical equilibrium, Gibbs free energy, enthalpy, and entropy. Also, included are how reaction rates are related between different substrates, different products; why there is only one independent variable in every reaction; what yield factors are, and how all are linked through stoichiometry. You should understand why A → B or S → P is used commonly in a reaction engineering text, instead of more realistic or real-life examples after reading this chapter. The understanding of how chemical reactions are approximated and represented, for example, is the key in understanding the representation of metabolic pathways in microbiology.
