CREDIT, HOURS and LOCATION: Three credit hours, meeting from MWF 9:10-10 a.m. in Rm. 108 JEB. OVERVIEW: CHEN 464 introduces the basic concepts of chemical kinetics and chemical reactor design and analysis. Emphasis is placed on homogeneous reactions occurring in batch, plug flow, and perfectly mixed flow reactors. Methods of analyzing data from these reactor types to determine the reaction order and mechanism are also discussed. COURSE OUTCOMES: By the end of the course, you should be able to do the following things: - Perform mass and energy balances on various reactors. Derive design equations based on the balance equations, assemble the concepts of reaction rates and mass & energy balances from mass and heat transfer. Apply the assembled knowledge to batch and continuous reactors. - Manipulate variables in the design equations to design reactors that achieve specific conversions and/or volumes under constraints. Investigate the effects of altering reaction kinetics, flow rate, temperature, or reactor type on conversion and/or reactor size. Demonstrate ability to manipulate reactor design mass & energy balances to incorporate reactions occurring in catalyst particles. Compute heat removal requirements for reactors. Contrast strengths and weaknesses of different reactor types. Recognize safety and environmental issues involved in reactor design. - Use computational software to solve reactor problems. Investigate complex reaction systems using PolyMath or other software. Analyze and comprehend the results for accuracy and rationality toward engineering judgments. - Recognize the general applicability of chemical engineering mass & energy balances and chemical kinetics. Apply mass & energy balances and chemical kinetics to new problems and applications. - Effectively perform in teams. Work effectively in teams and develop problem solving skills. PREREQUISITES: Thermodynamics, fluid mechanics, heat transfer, numerical methods, familiarity with computer software for numerical solution of ordinary differential equations, linear and nonlinear algebraic equations, regression, etc. (e.g. Polymath, MATLAB, Maple, Excel, Mathcad, Mathematica).

I will assign grades at the end of the course based on your average. Although the cutoffs will be determined based on the class distribution, the following can be guaranteed: > 90 will receive an A > 80 will receive at least a B > 70 will receive at least a C Regrading: If you believe that a homework exercise or an exam has been graded incorrectly, see the professor within one week after the work has been handed back. Write out on a separate sheet of paper what you believe to be in error. POLICY ISSUES: 1. The final is cumulative in this course 2. Make-up exams will only be given in the case of a well-documented emergency. 3. Attendance is strongly recommended though not enforced. In case you must be excused, please let me know in advance. 4. Out of courtesy to me and your fellow students, PLEASE come to class on time and please turn off cell phones or mute the ringer! HOMEWORK: (1) The weekly homework will be due at the beginning of class on the day it is DUE. Typically you will have a new homework on every Friday and the due is the next Friday. Late homework will be docked 20%, unless you have a Dean's Excuse. (2) Homework may be handwritten neatly. Use ink or dark pencil. The following items are not acceptable: very light pencil, writing on both sides of the paper, untrimmed pages torn from spiral notebooks, pages paper-clipped or folded together. (3) You are to make a group of three students of your own choice. However, each student must be able to solve every homework. (4) Solutions for the homework, as well as copies of lecture notes and examples, will be on the website (https://chesec.tamu.edu/classes/jeong/) Check Weekly! HOMEWORK HINTS: (1) There will be roughly ~ 10 homeworks given through the semester. Homework assignments must be done in groups of three people, with one paper handed in per group per assignment. Each member of the team will receive the same grade for each assignment. Please see the Teamwork Policy and Expectations section of the syllabus for more details. (2) TRY doing the homework BEFORE coming to the office hours. You'll get a lot more out of it if you do. (3) BTW - Copying or slightly modifying old solution sets that may be out there looks rather obvious and silly to the reader. But much worse is the fact that you are not really learning the material that way, as will become quite apparent at test time. (4) What I am really after is for you to learn from the homework. Remember exam problems are more or less similar to the homework problems. Thus it is very important for you to be able to solve homework problems if you want to do well in the exams. (5) The lowest grade on homework is thrown out, so don't sweat it if you miss one assignment. But don't blow off the homework entirely. INSTRUCTOR COMMITMENT: You can expect me to be courteous, punctual, well organized, and prepared for lecture and other class activities; to answer questions clearly and in a non-negative fashion; to be available during office hours or to notify you beforehand if they are unable to keep them; and to ensure uniform and consistent grading according to the posted guidelines.

TEAM POLICIES AND EXPECTATIONS TEAM COMPOSITIONS AND RESPONSIBILITIES: You may form groups for team homework assignments of three persons. These groups are voluntary and members may be changed at any time given mutual consent. Your team will have a number of responsibilities as it completes problem and project assignments. 1) Designate a coordinator, a recorder, and a monitor for each assignment, with each of these roles having responsibilities defined below. In teams of three, the same individual functions as monitor and checker. Rotate these roles for every assignment. 2) Agree on a common meeting time and what each member should have done before the meeting by way of preparation. 3) Do the required individual preparation. Each team member should attempt to outline the solution of each problem before the team meets. 4) Meet and work out the complete solutions to all assigned problems. Agree on next meeting time and roles for next assignment. 5) Review returned assignments. Make sure everyone understands why points were lost and how to correct errors. 6) Consult with the instructor if a conflict arises that can't be worked through by the team.
TEAM ROLES: 1) Coordinator checks with other team members before the meeting to remind them of when and where they will meet and what they are supposed to do, keeps everyone on task and makes sure everyone is involved during the meeting. 2) Recorder prepares final solution to be turned in. 3) Monitor makes sure everyone understands both the problem solutions and the strategies used to get them.

Note to monitors: If you ask people if they understand something and they say yes, you've learned nothing. To check for understanding in a way that means something, ask for an explanation. If someone on a team misses a problem on a test that is very much like a homework problem, the monitor has not done his/her job. Omitting names from completed assignments. If a student's name appears on a solution set, it certifies that he/she has participated in solving EACH of the homework problems in a given problem sets. If a team member refuses to cooperate on an assignment, his/her name should not be included on the completed work. Group work isn't always easy: team members sometimes cannot prepare for or attend group sessions because of other responsibilities, and conflicts often result from differing skill levels and work ethics. When teams work and communicate well, however, the benefits more than compensate for the difficulties. One way to improve the chances that a team will work well is to agree beforehand on what everyone on the team expects from everyone else.
