Surface Reactions and Nonideal Surfaces

The form of the Freundlich isotherm suggests immediately that simple, power-law forms might be applied successfully to surface reaction kinetics. Since the 

Given that rate expressions are nonunique to the kinetic sequence, and that 

Forms which bear resemblance to LH equations may actually represent situations far from that model, then why not 

Admit that what we have is an empirical rate equation, and 

For purposes of design and analysis use the simplest rate equation that will adequately fit the experimental data, that is, r = (Fa) (Fb)
