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))

Chemical Reaction Engineering
The reaction rate almost gets doubled for 10°C rise in temperature. This is due to the fact that the

Fraction of molecules having threshold energy increases
Collision frequency increases
Value of threshold energy decreases
Increased temperature reduces the activation energy
