Chapter 6: Isothermal Reactor Design: Molar Flow Rates

Liquid Phase CSTR

Hint 1: What are the mole balances for A and B?

Hint 2: What is the rate law?

$(a) V = \frac{F_{A0} - F_{A}}{-r_{A}} \textrm{,} V = \frac{F_{B}}{r_{B}}$

$(b) V = \frac{F_{A0} - F_{A}}{r_{B}} \textrm{,} V = \frac{F_{B}}{-r_{B}}$

$(c) V = \frac{\upsilon_{0}(C_{A0} - C_{A})}{-r_{A}} \textrm{,} V = \frac{\upsilon_{0}C_{B}}{-r_{A}}$

Hint 3: What is the combined rate law and mole balance?

$(a) V = \frac{\upsilon_{0}(C_{A0}-C_{A})}{k{C_{A}}^2}$

$(b) V = \frac{\upsilon_{0}C_{B}}{k{C_{A}}^2}$
