Chemical Reaction Engineering Sometimes, batch process is preferred over continuous process, when the product Both A & B Neither A nor B Sales demand is fluctuating Quality & yield can not be achieved in continuous processes, because of long residence time Both A & B Neither A nor B Sales demand is fluctuating Quality & yield can not be achieved in continuous processes, because of long residence time ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering During manufacture of H₂SO₄, the oxidation of SO₂ to SO₃ by oxygen is an en- dothermic reaction. The yield of SO₃ will be maximised, if the Temperature is increased Temperature is reduced and pressure is increased Pressure is reduced Temperature is increased and pressure is reduced Temperature is increased Temperature is reduced and pressure is increased Pressure is reduced Temperature is increased and pressure is reduced 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 1000 600 500 400 1000 600 500 ANSWER DOWNLOAD EXAMIANS APP
