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
