Kinetics of PCET Reactions

The free activation energy is determined by the driving force — AG°, which is related to the standard redox potential dilference (Aii°), and by the so-called reorganisation energy X (eqn (3.4)) 

102-105). Using this term for Hab, et can also be expressed in dependence of the donor acceptor distance (eqn (3.6)) 

Models accounting for the kinetic complexity of biological ET distinguish between true, gated and coupled ET (eqn (3.9), (3.10) and (3.11) ref. 100, 106, 

In a true ET reaction (eqn (3.9)) the ET will be the slowest and overall rate-limiting step. Experimentally observed 1-values report solely on ET and are 

The different characteristics of PT and ET events and their mutual influence discussed in the previous paragraph have to be accounted for in any mathematical approach. It is beyond the scope of this review to introduce the reader
