    • The adsorption of inhibitor compounds on metal surface will be chemisorptive if the activation energy measured for corrosion process in presence of these compounds remains unchanged or shows a slight tendency to decrease as compared with that obtained in blank solution (without inhibitor, In this regard, it is remarkable to notify that the increasing of activation barrier is generally accountable, because of corrosion rate decreasing in presence of inhibitor compounds, regardless the adsorption being physical or chemical. But, it should be justified for those situations in which the energy does not increase! This is because the energy referring here as the activation energy is not exactly the energy barrier, but includes the heat of inhibitor adsorption (ΔHads) as well. The latter quantity is significant for the case of chemical interactions (being highly negative) so that it can counterbalance the energy increasing
