Chemical Reaction Engineering For a first order isothermal chemical reaction in a porous catalyst, the effectiveness factor is 0.3. The effectiveness factor will increase if the Catalyst size is increased or the catalyst diffusivity is increased Catalyst size is reduced or the catalyst diffusivity is increased Catalyst size is increased or the catalyst diffusivity is reduced Catalyst size is reduced or the catalyst diffusivity is reduced Catalyst size is increased or the catalyst diffusivity is increased Catalyst size is reduced or the catalyst diffusivity is increased Catalyst size is increased or the catalyst diffusivity is reduced Catalyst size is reduced or the catalyst diffusivity is reduced 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 44015 7 6 3 44015 7 6 3 ANSWER DOWNLOAD EXAMIANS APP
