Chemical Reaction Engineering For a solid catalysed chemical reaction, the effectiveness of solid catalyst depends upon the __________ adsorption. Neither A nor B Physical Chemical Both A and B Neither A nor B Physical Chemical Both A and B ANSWER DOWNLOAD EXAMIANS APP
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)) 600 500 1000 400 600 500 1000 400 ANSWER DOWNLOAD EXAMIANS APP
