    (a) Develop a model that is consistent with the experimental data.
(b) Evaluate all the model parameters. For the second-order reaction

    with kCA0 = 0.01 min-1, a reactor volume of 1 m3, and a volumetric flow rate of 0.01 m3/min, determine the conversion of A:
(c) Using the model developed in part (a).
(d) Using the segregation model.
(e) Using the maximum mixedness model.
Also:
(f) What is the Peclet number?
(g) How many tanks in series are necessary to model the data above?
(h) For a first-order reaction with k = 0.07 min-1, what conversion is predicted by the dispersion model?
(i) Calculate the conversion for the first-order reaction for the tanks-in- series model (k = 0.07 min-1).
