10.3.7 Temperature Dependence of the Rate Law
Consider a surface-reaction-limited irreversible isomerization
in which both A and B are adsorbed on the surface, and the rate law is
The specific reaction rate, k, will usually follow an Arrhenius temperature dependence and increase exponentially with temperature. However, the adsorption of all species on the surface is exothermic. Consequently, the higher the temperature, the smaller the adsorption equilibrium constant. That is, as the temperature increases, KA and KB decrease resulting in less ...
