1 W’99FinalExam (25 pts) 1) The gas phase irreversible reaction A + B C is elementary. The entering flow rate of A is 10 mol/min and is equal molar in A and B. The entering concentration of A is 0.4 mol/dm 3 . a) What is the CSTR reactor volume necessary to achieve 90% conversion? b) What PFR volume is necessary to achieve 90% conversion? Additional Information k = 2 dm 3 /mol•min T 0 = 500 K Note: You do not need to use POLYMATH, but if you do write your program below in case you do not obtain the correct answer.
