Pick out the wrong statement below:
I. For the same conversion, the holding time required in a batch reactor, is always equal to the space time required in a PFR.
II. 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.
III. Arrehenius equation describing the effect of temperature on rate constant is given by, $${\text{K}} = {\text{A}}.{{\text{e}}^{ - \frac{{{\text{Ea}}}}{{{\text{RT}}}}}}$$
IV. 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 CH₃CHO is equal to K.C_CH3l.C_Hl and acts as a catalyst.
