A Century of Sabatiers Genius Idea

One classical misconception in general chemical kinetics, but particularly worrisome in catalysis, is the following  

S Myth A lower determining transition state will enhance the TOE Fact It may enhance the TOE, but only if the 5E is lowered. 

There are cases where a lower TDTS will actually reduce the efficiency of the reaction. This can be understood in an analysis of Sabatier s volcanos. 

If we want to understand the volcanos in the representation [30, 44], there is one more old instrument to add to the catalytic toolbox, the BEP principle (by Bell - Evans-Polanyi [8]), which can be written as 

In this scheme, three similar catalysts are depicted, each one with a different Ef. Catalyst A has an exergonic formation energy 12 f 0), and its energy span
