Chemical Reaction Engineering In a zero order reaction, reactants concentration does not change with time and the Time for half change is independent of the initial concentration Reaction rate is trebled when the initial concentration is trebled Time for half change is half the time taken for completion of the reaction Time for completion of the reaction is independent of the initial concentration Time for half change is independent of the initial concentration Reaction rate is trebled when the initial concentration is trebled Time for half change is half the time taken for completion of the reaction Time for completion of the reaction is independent of the initial concentration 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)) 400 600 1000 500 400 600 1000 500 ANSWER DOWNLOAD EXAMIANS APP
