Chemical Reaction Engineering The reaction rate almost gets doubled for 10°C rise in temperature. This is due to the fact that the Increased temperature reduces the activation energy Fraction of molecules having threshold energy increases Collision frequency increases Value of threshold energy decreases Increased temperature reduces the activation energy Fraction of molecules having threshold energy increases Collision frequency increases Value of threshold energy decreases 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 Higher in CSTR Same in both the reactors Data insufficient; can't be predicted Higher in P.F. reactor Higher in CSTR Same in both the reactors Data insufficient; can't be predicted Higher in P.F. reactor 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)) 500 1000 600 400 500 1000 600 400 ANSWER DOWNLOAD EXAMIANS APP
