Let’s continue Problem P13-19B.

(a) What would be the conversion for a second-order reaction with kCM) = 0.1 min−1 and CA0 = 1 mol/dm3 using the segregation model?

---

(b) What would be the conversion for a second-order reaction with kCA0 = 0.1 min−1 and CA0 = 1 mol/dm3 using the maximum mixedness model?

---

(c) If the reactor is modeled as tanks in series, how many tanks are needed to represent this reactor? What is the conversion for a first-order reaction with k = 0.1 min−1?

---

(d) If the reactor is modeled by a dispersion model, what are the Peclet numbers for an open system and for a closed system? What is the conversion for a first-order reaction with k = 0.1 min−1 for each case?

---

(e) Use the dispersion model to estimate the conversion for a second-order reaction with k = 0.1 dnvVmol-s and CA0 = 1 mol/dm3.

---

(f) It is suspected that the reactor might be behaving as shown in Figure P14-13B, with perhaps (?) V, = V2. What is the “backflow” from the second to the first vessel, as a multiple of υ0 ?

---

Proposed model system

(g) If the model above is correct, what would be the conversion for a second-order reaction with k = 0.1 dm3/mol-min if CA0 = 1.0 mol/dm3?

---

(h) Prepare a table comparing the conversion predicted by each of the models described above.

---

(i) How would your answer to part (a) change if the reaction were carried out adiabatically with the parameter values given in Problem P13-2A(j)?
