A reactor has flow characteristics given by the nonnormalized C curve in Table P14.11, and by the shape of this curve we feel that the dispersion or tanks-in-series models should satisfactorily represent flow in the reactor.

(a) Find the conversion expected in this reactor, assuming that the dispersion model holds.

(b) Find the number of tanks in series which will represent the reactor and the conversion expected, assuming that the tanks-in-series model holds.

(c) Find the conversion by direct use of the tracer curve.

(d) Comment on the difference in these results, and state which one you think is the most reliable.
