Book 12 Molecular States version 2.0 introduces the new concept of a molecular state. This concept was created in 1973 to facilitate the analysis of a small chemical system that had multiple phases and interfaces. For example, each different phase had a volume fraction and each interface had a surface-to-volume ratio. In each molecular state, a selected molecule could undergo one or more of the following rate processes: diffusion, convection, reaction.
This simple approach allows a student to obtain a deep understanding of the essential characteristics of partition chromatography, multiphase catalysis, steady-state fixed-bed reactor, non-steady-state batch reactor, and steady-state countercurrent separation. Algebra is the only mathematics that is required.
