The adiabatic exothermic irreversible gas-phase reaction

is to be carried out in a flow reactor for an equimolar feed of A and B. A Levenspiel plot for this reaction is shown in Figure P2-9B on the next page.

(a) What PFR volume is necessary to achieve 50% conversion?

---

(b) What CSTR volume is necessary to achieve 50% conversion?

---

(c) What is the volume of a second CSTR added in series to the first CSTR (Part b) necessary to achieve an overall conversion of 80%?

---

(d) What PFR volume must be added to the first CSTR (Part b) to raise the conversion to 80%?

---

(e) What conversion can be achieved in a 6 × 104 m3 CSTR and also in a 6 × 104 m3 PFR?

---

(f) Critique the shape of Figure P2-9B and the answers (numbers) to this problem.
