Beyond Arrhenius to the Eyring Transition State

we can show Eyring s genius in reinterpreting the Arrhenius formula. According to Eyring s theory, there is in almost every reaction a key transition state. Rather than just use the extent of reaction in moles to treat the overall reaction turnover, the Eyring treatment imagines some molecular distortion of the internal coordinates of the combined activated complex, which 

FIGURE 8.1 Henry Eyring developed the theory of the kinetic transition state. F rof. Eyring published more than 680 research papers and was an enthusiastic lecturer. Perhaps, his most important contribution to physical chemistry was the formulation of the transition-state concept in chemical reactions.

Let us carefully consider the part of this process. It means that many times, the activated 

Eyring s transition-state theory was developed in the 1930s and strained every computational capability at that time. Now it is possible to use modem computer programs to study the rearrangement of the reactants along a reaction coordinate, which is different from the extent of reaction  

Their results and others were reviewed later in 1976 by D. G. Truhlar [4] who also investigated that reaction with more modem computer programs only to find that the early work by Eyring et al. was mainly qualitative. Even so, Eyring had an understanding of the basic concepts but not the means to do accurate calculations.
