Data Treatment in Kinetics

subject

description

Chemical kinetics is an important part of chemistry devoted to study how reactions proceed and quantify the rate of the process. The reaction mechanism is the chemical model that describes how the chemical change occurs. From the proposed mechanism, a mathematical model can be obtained to explain the evolution of the chemical species with time. In many cases, the mechanism can be simplified to a single rate law that relates the reaction rate with concentrations. In the last decades, the study of kinetic systems has benefited from the development of instrumentation, the increasing availability of specialized computer software, and the advances in data treatment techniques. A comprehensive review of data treatment in kinetics is presented here from a practical viewpoint. The different factors that influence the reaction kinetics are summarized. Finally, how to take advantage of the kinetic information contained in the experimental data with an analytical aim is described. Keywords: chemical kinetics; data treatment; rate law; reaction mechanism; Laplace transform; least-squares regression; kinetic methods of analysis; multivariate analysis
