Abstract

The concept of extent of reaction permits the definition of the related variable, degree of advancement. The expression of the concentrations in the reaction rate equation as a function of one degree of advancement variable leads to considerable simplification of the mathematical problem and yields a single differential equation to solve. However, the misuse of these concepts leads to wrong results, which have survived for 40 years even in textbooks on chemical kinetics. In fact, the definition of one degree of advancement variable for each elementary reaction step is required in the case of multistep reactions.

- What Is a Reaction Rate?
  Guy Schmitz
  Journal of Chemical Education2005 82 (7), 1091
  Experimentally, the rates of reactant consumption or rates of product formation are measured. These rates are related to, but different from, reaction rates. A reaction rate is a property of a given reaction, not of chemical species. The relationships ...
