Document Content and Description Below

Ch En 386 Winter 2016 Homework #9 due at 9 a.m. on Wednesday, January 27 Note: Anytime you solve a problem with Polymath or MathCad, you must print a copy of the report (Polymath) or the page wit ... h equations (MatchCad). HW #9: CSTR 1. (2 points) Conditioning, magnitude, and reasonableness problems a. For A + 2B Æ C in a steady state flow reactor, show the relationship between XA and XB in terms of inlet flow rates of the two species. b. Under what conditions (name two) is v=v0 for a flow reactor involving a liquid. c. For a CSTR, when is VR = FA0XA/(-rA) never true? 2. (4 points) A reversible liquid-phase isomerization A ↔ B is carried out isothermally in a 1000-gal CSTR. Only pure A enters the reactor. The reaction is second order in both the forward and reverse directions. The reaction is reversible with KC = 3.0 at 300 K. 'Hrxn is -25,000 cal/mol (you may assume constant) and E = 15,000 cal/mol. At 300 K, the conversion in the CSTR is 40%. Make a plot of XA vs T from 300 to 330 K in increments of at least 5 K to determine the temperature that would give the maximum conversion. Why is there a maximum? Show any computer work you use to obtain your answer. [Show More]
