CHE 211 Introduction to Chemical Processing Fall 2007
Midterm Exam #1 Review
The midterm exam will cover material from chapters 2-5, but the focus will be on chapters 4 and 5. It will
consist of 10 multiple choice questions, 1 problem from the homework, and 2 other problems, which should
be similar to problems from lecture and the homework. To prepare, I would focus on the lecture notes and
homework, but do not neglect the book entirely. The exam will be OPEN BOOK, but NOT OPEN NOTES.
You should bring the textbook (DO NOT FORGET IT) and a calculator.
Introduction to Engineering Calculations
•Understand units and unit conversion
•force vs. weight
Processes and Process Variables
•Know how density and flow rate is defined
•Be able to calculate chemical compositions of a mixture
•absolute vs. gauge pressure
Fundamentals of Material Balances
•Know how to classify a process
•Know when and how to write a mass balance
•Know how to handle multiple units and recycle streams
•Know how to handle reactions (extent of reaction, ξ, or atomic balances) — there will be a problem
on this topic
•Combustion reactions
Single-Phase Systems
•Ideal gas law - use and assumptions
•EOS for nonideal gases (van der Waal, SRK, etc.)
•Compressibility factor
