Chemical Reaction Engineering For multiple reactions, the flow pattern within the vessel affects the Size requirement Neither A nor B Distribution of reaction products Both A and B Size requirement Neither A nor B Distribution of reaction products 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)) 600 400 500 1000 600 400 500 1000 ANSWER DOWNLOAD EXAMIANS APP

Chemical Reaction Engineering With the same reaction time, initial concentration and feed rate, the reaction 2A → B is carried out separately in CSTR and P.F. reactor of equal volumes. The conversion will be Same in both the reactors Higher in P.F. reactor Data insufficient; can't be predicted Higher in CSTR Same in both the reactors Higher in P.F. reactor Data insufficient; can't be predicted Higher in CSTR ANSWER DOWNLOAD EXAMIANS APP
