Principle in Chemical Kinetics

Based on the results obtained in the investigation of the effects of modulation of the electron density by the nuclear vibrations, a lability principle in chemical kinetics and catalysis (electrocatalysis) has been formulated in Ref. 26. This principle is formulated as follows the greater the lability of the electron, transferable atoms or atomic groups with respect to the action of external fields, local vibrations, or fluctuations of the medium polarization, the higher, as a rule, is the transition probability, all other conditions being unchanged. Note that the concept lability is more general than 

The lability of the transferable electrons or atoms influences all the factors in the expression for the reaction rate constant, 

Smaller values of the activation free energy, Fa, due to the distortion of the shape of the free energy surfaces. 

Larger values of the transmission coefficient, k, due to improved overlapping of the wave functions of quantum particles (electrons, protons, etc.).
