and others in support of the "master reaction" theory. Burton (36) 

 has been the chief critic of the theory, basing his objections on the 

 law of mass action. He beheves that if one reaction is to dominate 

 over another in the same reaction chain at one temperature but may 

 in turn be dominated by another reaction at another temperature, the 

 temperature characteristic of the two reactions would have to vary b>' 

 a larger interval than that actually observed. By mathematical 

 analysis, Burton proposes that the slope of the line of an Arrhenius 

 plot may result from pace-setting shared by several reactions of dif- 

 ferent critical increments rather than control by a master reaction. 

 Both Burton's criticism and Crozier's original suggestions fail to 

 offer any explanation of an Arrhenius plot with regard to underlying 

 mechanisms. Johnson, Eyring, and co-workers have extended the 

 work of other investigators to develop the theory of rate processes. 

 Additional information on this subject may be found in the book by 

 Glasstone, Laidler, and Eyring (37).
