Chemical Reaction Engineering The knowledge of initial concentration and rate constant is necessary to determine the half life time of a reaction of __________ order. None of these Zero Second First None of these Zero Second First 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
