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)) 500 400 1000 600 500 400 1000 600 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering The reaction rate almost gets doubled for 10°C rise in temperature. This is due to the fact that the Value of threshold energy decreases Fraction of molecules having threshold energy increases Collision frequency increases Increased temperature reduces the activation energy Value of threshold energy decreases Fraction of molecules having threshold energy increases Collision frequency increases Increased temperature reduces the activation energy ANSWER DOWNLOAD EXAMIANS APP
