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 6 44015 3 7 6 44015 3 7 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering The reaction rate almost gets doubled for 10°C rise in temperature. This is due to the fact that the Fraction of molecules having threshold energy increases Collision frequency increases Value of threshold energy decreases Increased temperature reduces the activation energy Fraction of molecules having threshold energy increases Collision frequency increases Value of threshold energy decreases Increased temperature reduces the activation energy ANSWER DOWNLOAD EXAMIANS APP
