A. For a first order consecutive reaction, a tubular flow reactor as compared to a stirred tank
reactor provides higher overall selectivity
B. For an ideal mixed reactor at steady state, the exit stream has the same composition as fluid
within the reactor and the space time is equivalent to holding time for constant density system
C. Plug flow reactor (PFR) is always smaller than mixed reactor for all positive reaction orders
for a particular duty
D. Reaction rate does not decrease appreciably as the reaction proceeds in case of an
autocatalytic reaction
Correct Answer: A. For a first order consecutive reaction, a tubular flow reactor as compared to a stirred tank
reactor provides higher overall selectivity ✔
