Chemical Reaction Engineering The gas phase reaction 2A ⇋ B is carried out in an isothermal plug flow reactor. The feed consists of 80 mole % A and 20 mole % inerts. If the conversion of A at the reactor exit is 50%, then CA/CA0 at the outlet of the reactor is 43833 43959 43898 43864 43833 43959 43898 43864 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 6 7 3 44015 6 7 3 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering A second order reaction of the form A + B → C is called a pseudo-first order reaction, when CB0 > CA0 CA0 = CB0 CA0 > CB0 CB0 ≥ CB0 CB0 > CA0 CA0 = CB0 CA0 > CB0 CB0 ≥ CB0 ANSWER DOWNLOAD EXAMIANS APP
