A. For the same conversion, the holding time required in a batch reactor, is always equal to the space time required in a PFR
B. Two mixed reactors of unequal size are available for producing a specified product, formed by
a homogenous second order reaction. To achieve maximum production rate, the smaller
reactor should be placed in series before the larger reactor
C. Arrhenius equation describing the effect of temperature on rate constant is given by,
K = A.e-Ea/RT
D. The mechanism for the decomposition of CH3CHO into CH4 and CO in presence of I2 is:
CH3CHO + I2 → CH3I + HI + CO; slow
CH3I + HI → CH4 + I2; fast
Then the rate of disappearance of CH3CHO is equal to K.CCH3I.CHI and acts as a catalyst
