Chemical Reaction Engineering
For a heterogeneous catalytic reaction

A relatively small amount of catalyst can cause the conversion of large amount of reactants which does not mean that catalyst concentration is important
The surface of the catalyst does not play an important role during reaction
The catalyst does not form an intermediate complex with the reactant
Free energy of activation is lowered in the presence of catalyst, which remains unchanged at the end of reaction

In Langmuir treatment of adsorption,

Extent of adsorption is more than one complete monomolecular layer on the surface
All the adsorption does not take place by the same mechanism
Whole surface of the catalyst is essentially uniform and the adsorbed molecule has no effect on the rate of adsorption per site
Whole surface of the catalyst does not have the same activity for adsorption and there is attraction between the adsorbed molecule
