Chemical Reaction Engineering In Langmuir treatment of adsorption, All the adsorption does not take place by the same mechanism Whole surface of the catalyst does not have the same activity for adsorption and there is attraction between the adsorbed molecule 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 All the adsorption does not take place by the same mechanism Whole surface of the catalyst does not have the same activity for adsorption and there is attraction between the adsorbed molecule 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 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering 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 kmole/m³ , the volume of the mixed flow reactor should be increased by a factor of 7 6 3 44015 7 6 3 44015 ANSWER DOWNLOAD EXAMIANS APP
