Chemical Reaction Engineering With increase in the order of reaction (for all positive reaction orders), the ratio of the volume of mixed reactor to the volume of plug flow reactor (for identical feed composition, flow rate and conversion) Decreases Increases Remains same Increases linearly Decreases Increases Remains same Increases linearly ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Pick out the wrong statement pertaining to space velocity of flow reactors. None of these The unit of space velocity is (time)⁻¹ The space velocity of 3 hr⁻¹ means that one third reactor volume of feed at specified conditions are being fed into the reactor The space velocity of 3 hr⁻¹ means that three reactor volumes of feed at specified conditions are being fed into the reactor every hour None of these The unit of space velocity is (time)⁻¹ The space velocity of 3 hr⁻¹ means that one third reactor volume of feed at specified conditions are being fed into the reactor The space velocity of 3 hr⁻¹ means that three reactor volumes of feed at specified conditions are being fed into the reactor every hour ANSWER DOWNLOAD EXAMIANS APP
