Isothermal Continuous Stirred Tank Reactor (CSTRs): ConcepTest and Example Problem

Try to answer this ConcepTest and solve this example problem before using this module. Studies show that trying to answer the questions before studying material improves learning and retention. By the end of this module, you should be able to answer these on your own. Answers will be given later in this module.

Example Problem 1

The hydrolysis of acetic anhydride to form acetic acid is carried out in a 1250-L CSTR. The feed is 2.5 mol/L acetic anhydride and 50. mol/L of water. The reaction:
(CH3CO)2O + H2O ⇋ 2CH3COOH
is first order in (CH3CO)2O and first order in H2O. At the reactor temperature, the rate constant is 0.075 L/(mol s). The feed flow rate is 15 L/s. What is the conversion of acetic anhydride?
