Chemical Reaction Engineering For a heterogenous catalytic reaction, A + B → C, with equimole feed of A and B, the initial rate - rA0 is invariant with total pressure. The rate controlling step is Desorption of C Surface Kc/(1 + TS) reaction between absorbed A and B in the gas phase Surface reaction between A in the gas phase and absorbed B Surface reaction between absorbed A and absorbed B Desorption of C Surface Kc/(1 + TS) reaction between absorbed A and B in the gas phase Surface reaction between A in the gas phase and absorbed B Surface reaction between absorbed A and absorbed B 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 3 44015 6 7 3 44015 6 ANSWER DOWNLOAD EXAMIANS APP
