The experiments on reaction A → B were carried out and the conversion-rate data is given in Table P2-11.

a. What are the batch reactor times to achieve 10%, 50%, and 80% for the reactor A → B when the initial concentration is 2 molar?
b. Plot the reaction rate, –rA, as a function of time up to a time necessary to achieve 80% conversion. Additional Homework Problems can be found on the CRE Web site under Chapter 2 A.
