Abstract

Abstract:

Kinetic data treatment is one of the paramount contents of the kinetics in physical chemistry. There have been imperfections in the classical kinetic data treatment when faced with modern monitoring techniques which can supply extensive experimental data. Recently, variable time normalization analysis is raised to solve the above problems. With only several experiments under real experimental conditions, the rate constant and reaction order of the reactants and catalyst can be deduced by using visual comparison with the help of spreadsheet.

Key words: Kinetic data, Reaction order, Integration method, Visual method
