Denbigh s reaction

From our viewpoint one of the most interesting of Denbigh s papers is his contribution to the First European Symposium on Chemical Reaction Engineering (Denbigh, 1958). He considered the... 

Historically, the use of microreactors dates back to the 1940s when they were developed to measure kinetics of catalytic reactions.One of the key early findings was Denbigh s 1965 observation that if a reactor were made small enough, temperature and concentration gradients with the reactor would be negligible, so that differential (i.e., gradientless) behavior would be observed. This allowed much more accurate kinetic... 

There are only three independent chemical reactions among these five reactions [see Problem 8.9(c)] This is easily demonstrated using Denbigh s method (cf. Sec. 8.3) we start by writing the reactions... 

Denbigh s Principles of Chemical Equilibrium is divided into three parts, in which the principles of thermodynamics, reaction and phase equilibria, and statistical mechanics and its relation with thermodynamics are developed. The book particularly takes note of the practical side of the subject and gives numerous illustrations of applications to experiment. 

The aim of Denbigh s volume is to develop the general theory of equilibrium, including its statistical treatment, with problems to illustrate numerous practical applications. It is assumed that the student is already very familiar with the concepts of temperature and heat and that he already has some knowledge of thermodynamics. It is recognized that thermodynamics needs to be studied several times over at advancing levels. Part I presents a traditional development of the subject. Part II presents reaction and phase equilibria, and Part III develops statistical thermodynamics. 

We can find the reaction s equilibrium point from Equation 3.3 as soon as we know the form of the function representing chemical potential. The theory of ideal solutions (e.g., Pitzer and Brewer, 1961 Denbigh, 1971) holds that the chemical potential of a species can be calculated from the potential pg of the species in its pure form at the temperature and pressure of interest. According to this result, a species chemical potential is related to its standard potential by...
