The kinetics of the aqueous phase decomposition of A is investigated in two CSTR reactors in series, the second reactor having twice the volume of the first reactor. At steady state with a feed concentration of 1 mil of A liters and the mean residence time of 96 seconds in the first reactor, the concentration in the first reactor is 0.5 mol of Aliter and in the second is 0.25 mol of the A liter. Find the kinetic equation for the decomposition.

During the liquid phase decomposition of A, two reactions compete. A one-half order reaction (k1 = 0.025 mol1/2/L1/2/sec) produces the desired product; whereas, a first order reaction (k2 = 0.008/sec) produces an unwanted impurity. The initial concentration of A to be used is 8 mol/L and 75% conversion of A is required. a) (7 points) If a CSTR is used to achieve this conversion, what would be the overall yield and selectivity of the desired product? b) (4 points) What...

Consider a system with two CSTRs in series (i.e., the output from the first reactor becomes the input to the second reactor). Assume a pollutant enters the system and undergoes first-order decay with a rate constant k. (a) What mean residence time, θ = V/Q, is required in the first reactor to achieve 90 percent removal in that reactor (i.e., C1/Cin = 0.1, where C1 is the steady-state outlet concentration for a fixed inlet concentration Cin)?
