For identical conversions, the residence time in a batch reactor is always the same as the space time in a plug flow reactor (PFR).Given two mixed reactors of different volumes used for producing a product via a second-order homogeneous reaction, placing the smaller reactor before the larger one in series maximizes the production rate.The Arrhenius equation, which relates the temperature to the rate constant, is expressed as: K = A·e^(-Ea/RT).The decomposition of CH3CHO into CH4 and CO in the presence of I2 proceeds through: CH3CHO + I2 → CH3I + HI + CO (slow step), followed by CH3I + HI → CH4 + I2 (fast step), where I2 acts as a catalyst.

Explanation

Option A is incorrect because, for the same conversion, the holding time in a batch reactor does not always equal the space time in a PFR. The other statements are accurate: B describes optimal reactor arrangement for maximum production in a second-order reaction; C correctly states the Arrhenius equation; and D outlines the catalytic mechanism of CH3CHO decomposition involving I2.
