The Elovich equation and chemisorption kinetics

Abstract

A generalized Elovich equation which takes account of features of chemi- sorption not previously included is presented and discussed. A systematic procedure for determining the parameters, the initial rates, and the corresponding apparent activation energy is described.

A method based on a linear regression analysis which is capable of evaluating the parameters more satisfactorily than graphical and numerical methods is proposed and applied to a range of existing experimental data.
