Rate constants and radius of curvature

The equilibrium constant for an elementary reaction is the ratio of the rate constants of the two opposed reactions and depends on the radii of curvature this means that these rate constants also depend on the radii of curvatures. 

Rate- determining step Space function E (f] Kinetic law 

Consider an elementary step that passes through an activated state indicated by 

According to section 3.11.1, the Gibbs energy of activation is the Gibbs energy of the first step X and is given by a relation of the form  

The sum included in this expression relates to molar volumes of the solid con5)onents that are involved in the activation step, that is, the volume of the initial state and the one of the activated state.
