CHEMICAL REACTION ENGINEERING QUIZ

In Langmuir treatment of adsorption,

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

Extent of adsorption is more than one complete monomolecular layer on the surface

Whole surface of the catalyst does not have the same activity for adsorption and there is attraction between the adsorbed molecule
