Chemical Reaction Engineering The reaction A → B is conducted in an adiabatic plug flow reactor (PFR). Pure A at a concentration of 2 kmol/m³ is fed to the reactor at the rate of 0.01 m³ /s and at a temperature of 500 K. If the exit conversion is 20%, then the exit temperature (in k)is (Data: Heat of reaction at 298 K = - 50000 kJ/ kmole of A reacted Heat capacities CPA = CPB = 100kJ/kmole. K (may be assumed to be independent of temperature)) 1000 400 600 500 1000 400 600 500 ANSWER DOWNLOAD EXAMIANS APP
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 Surface Kc/(1 + TS) reaction between absorbed A and B in the gas phase Desorption of C Surface reaction between A in the gas phase and absorbed B Surface reaction between absorbed A and absorbed B Surface Kc/(1 + TS) reaction between absorbed A and B in the gas phase Desorption of C Surface reaction between A in the gas phase and absorbed B Surface reaction between absorbed A and absorbed B ANSWER DOWNLOAD EXAMIANS APP
