In Langmuir treatment of adsorption,_________________?
Correct answer: C. Whole surface of the catalyst is essentially uniform and the adsorbed molecule has no effect
- A. Whole surface of the catalyst does not have the same activity for adsorption and there is
- B. attraction between the adsorbed molecule
- C. Whole surface of the catalyst is essentially uniform and the adsorbed molecule has no effect
- D. on the rate of adsorption per site
- E. All the adsorption does not take place by the same mechanism
- F. Extent of adsorption is more than one complete monomolecular layer on the surface
Explanation
Langmuir theory assumes a uniform surface with identical adsorption sites, no interaction between adsorbed molecules, and formation of only a monolayer. Thus option c states the relevant assumptions, unlike the options suggesting surface variation or multilayer adsorption.

A pollutant P degrades according to first order kinetics. An aqueous stream containing P at 2 kmole/m3 and volumetric flow rate 1m3 /h requires a mixed flow reactor of volume V to bring down the pollutant level to 0.5 kmole/m3. The inlet concentration of the pollutant is now doubled and the volumetric flow rate is tripled. If the pollutant level is to be brought down to the same level of 0.5 k.mole/m3, the volume of the mixed flow reactor should be increased by a factor of_______________?
