Chemical Reaction Engineering Cold shot cooling is only practical when the feed temperature is __________ than the reaction temperature. Higher Lower Much lower Much higher Higher Lower Much lower Much higher ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering The knowledge of initial concentration and rate constant is necessary to determine the half life time of a reaction of __________ order. None of these Second First Zero None of these Second First Zero 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)) 1000 400 500 600 1000 400 500 600 ANSWER DOWNLOAD EXAMIANS APP
