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 Pick out the wrong statement pertaining to space velocity of flow reactors. None of these 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 The unit of space velocity is (time)⁻¹ None of these 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 The unit of space velocity is (time)⁻¹ ANSWER DOWNLOAD EXAMIANS APP
