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
Chemical Reaction Engineering In a zero order reaction, reactants concentration does not change with time and the Time for completion of the reaction is independent of the initial concentration Time for half change is half the time taken for completion of the reaction Time for half change is independent of the initial concentration Reaction rate is trebled when the initial concentration is trebled Time for completion of the reaction is independent of the initial concentration Time for half change is half the time taken for completion of the reaction Time for half change is independent of the initial concentration Reaction rate is trebled when the initial concentration is trebled ANSWER DOWNLOAD EXAMIANS APP
