Abstract

With certain kinetic systems it may be reasonably assumed that the concentrations of some or all of the participating species do not change appreciably with time. This assumption of time-invariance may be applied, for example, to all species for a volume element in a fixed position within a flow system, or to particular species, such as reactive intermediates in a static system. In such cases, the concentrations of these species are maintained in a dynamic balance of steady state by the interaction of opposing processes which may be either physical or chemical in origin: bulk flow of material, diffusion, and precipitation constitute typical physical processes, while chemical processes may originate from thermal, photochemical, or electrochemical sources. In this chapter two important types of steady-state systems are discussed. These are the flow system, in which the physical process of flow is opposed by the chemical process of reaction, and the radical-chain system in which the opposing acts of formation and removal of reactive intermediates occur by chemical processes.
