A reversible, elementary liquid reaction 2A B is carried out in a continuous stirred tank reactor (CSTR). The concentration of A in the inlet stream is 10 mol/dm?. No B is present in the inlet stream. The volumetric flow rate is 5 dm2/min for both inlet and outlet streams. (a) (10 points) Write down the rate expression for the disappearance of A (ra) in terms of rate constant (ka), the equilibrium constant (K), and the concentrations of species A and B (CA and CB respectively). Express the units for ka and K in terms of mol, dm?, and min. (b) (10 points) If the reaction is carried out at 100 C, and the reaction constant ka has a pre- exponential factor A = 1043 min - and an activation energy of 85 kJ/mol, what is the temperature to make a doubled? (R = 8.314 J/mol.K)). (c) (15 points) What is the size of the CSTR reactor to achieve the concentration of B at 4 mol/dmin the outlet stream? Assume that the reverse rate constant of the reaction k-A = ka/10, and the operation temperature at 100 C. =
