Chemical Equilibria and Kinetics in Soils [Hardcover]

This book clearly illustrates the limitations of using chemical thermodynamics to describe chemical phenomena in soils--especially with regard to kinetics and molecular mechanisms--and proposes that the quantitative description of soils is not complete without adequate characterization of the rates of the chemical reactions. The author, a renowned authority in the field, focuses on reactions in the soil solution and considers aqueous phase properties. He also cogently draws distinctions between thermodynamic chemical species and kinetic chemical species. This critical introduction to the use of chemical thermodynamics and kinetics for describing reactions in the soil solution will appeal not only to professionals but to students as well.
