The kinetics of activated chemisorption are described by plots of the time t against the reciprocal of the rate of adsorption Z=(dq/dt)–1. The parameter t0 of the Elovich equation q=(1/b) ln ab+(1/b) ln (t+t0) where a, b and t0 are constants is estimated from the plot of t against Z. The plot of q against log(t+t0) is convex towards the q axis at low t indicating that the Elovich equation is not obeyed in that range. The “combined model” of Aharoni and Tompkins predicts a curvature in the wrong direction and is inapplicable without modification.
Aharoni et al. (Thu,) studied this question.
