Sample Question
Question: A steady-state CSTR operates at 350 K with a first-order irreversible reaction (k = 0.04 s−1). The feed concentration is 2.0 mol/L and the reactor volume is 500 L with a volumetric flow rate of 10 L/s. What is the exit concentration?
(A) 0.33 mol/L
(B) 0.67 mol/L
(C) 1.00 mol/L
(D) 1.33 mol/L
View Solution
For a first-order reaction in a CSTR, the design equation gives:
CA = CA0 / (1 + k · tau)
Space time: tau = V / v = 500 / 10 = 50 s
CA = 2.0 / (1 + 0.04 × 50) = 2.0 / (1 + 2) = 2.0 / 3 = 0.67 mol/L
Answer: (B)
How to Use This Book Effectively
Chemical engineering covers a wide range of interconnected topics. Here is how to make the most of your practice time:
- Start with a topic inventory. Skim the table of contents and honestly assess which topics you remember well and which ones have faded. Focus your early study time on your weakest areas.
- Master the fundamentals first. Mass and energy balances, thermodynamics, and reaction engineering form the core of the exam. Get these topics solid before branching into process control and safety.
- Work problems with the handbook. Practice finding steam tables, conversion factors, and key equations in the NCEES FE Reference Handbook. On exam day, fast handbook navigation saves valuable minutes.
- Time yourself. Once you are comfortable with the material, work through sets of 20+ problems at exam pace (about 2.9 minutes per question).
- Review every solution thoroughly. The detailed solutions in this book often show alternative approaches and common pitfalls. Understanding why wrong answers are wrong is just as valuable as getting the right one.

Frequently Asked Questions
What is the pass rate for the FE Chemical exam?
The FE Chemical exam pass rate for first-time test takers from ABET-accredited programs is typically around 70–80%. The rate drops significantly for repeat takers and those testing more than a few years after graduation. Thorough practice with exam-realistic questions is one of the most effective ways to improve your chances.
What makes the FE Chemical exam different from other FE disciplines?
The FE Chemical exam has heavy emphasis on chemical engineering-specific topics like mass and energy balances, chemical reaction engineering, process design, and transport phenomena. While it shares common topics like mathematics, ethics, and economics with other FE exams, roughly 60% of the questions are unique to chemical engineering.
Should I study the NCEES FE Reference Handbook before using this practice book?
You can use them in parallel. Start solving problems from this book and reference the handbook as you work through solutions. This builds familiarity with the handbook naturally. By exam day, you should know where every key formula, steam table, and conversion factor is located.
