The hydrolysis of methyl acetate is an autocatalytic reaction (catalyzed by acetic acid) and is first order with respect to both methyl acetate and acetic acid. ki CH3COOCH3 + H2O + CH3COOH + CH3OH The following data are given: Initial concentration of methyl acetate = 0.45 gmol/l Initial concentration of acetic acid = 0.045 gmol/l The conversion in 1 hour is 65% in a batch reactor.

An autocatalytic reaction A+ B 2B, r=kCACB occurs in a plug flow reactor (PFR). A small amount of autocatalyst (B) is supplied in the feed, with FBo/FA0 = CB0/CAo = 0.02. The design equation for the PFR is -Xas 1 kC AOT = (1 - XA)(0.02 + XA) For XA1 = 0.8, compute kC Aor by using information on f(0.1n), n = 0-8, and employing Simpson's rule.

In an autocatalytic chemical reaction, the product formed is a catalyst for the reaction. If Q0 is the amount of the original substance and x is the amount of catalyst formed, the rate of chemical reaction is dQ dx = kx(Q0 − x) For what value of x will the rate of chemical reaction be greatest? x =

6.11. Consider the autocatalytic reaction A R, with -r0.001 CACR mol/ liter s. We wish to process 1.5 liters/s of a CAo 10 mol/liter feed to the highest conversion possible in the reactor system consisting of four 100- liter mixed flow reactors connected as you wish and any feed arrangement.

An autocatalytic chemical reaction is one in which the product is also one of the reactants. Consider an autocatalytic reaction in which chemicals A and B combine to form the chemical B. Suppose that the rate of the reaction (the rate at which the amount of 13 changes) is proportional to the product of the instantaneous amounts of A and B present at a given time.

Question: enzyme is autocatalytic, meaning it produces additional enzyme through the reaction. The schematic of this is: E+S --> ES ---(k3)---> E+E Determine the rate law for the enzyme, E, in terms of only [E] and [S]. forward rate constant is k1and the reverse rate constant is …

Question: In bioreactors, the growth is autocatalytic in that the more cells you have, the greater the growth rate cells Cells + nutrients more cells + product The cell growth rate, rg, and the rate of nutrient consumption, rs, are directly proportional to the concentration of …

Consider the autocatalytic, liquid-phase reaction A+R→2R, carried out in an adiabatic CSTR. The reaction is exothermic, and the rate law is given by r=k(T)cAcR, where the second-order rate constant k(T) has the usual Arrhenius form.
