Chemical Reaction Engineering For identical flow rate, feed composition and for elementary first order reactions, 'N' equal sized mixed reactors in series with a total volume 'V' gives the same conversion as a single plug flow reactor of volume 'V' for constant density systems. This is true, when the value of 'N' is >1 ≥1 1 ∞ >1 ≥1 1 ∞ ANSWER DOWNLOAD EXAMIANS APP
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 linearly Increases Remains same Decreases Increases linearly Increases Remains same ANSWER DOWNLOAD EXAMIANS APP
