Chemical FE Exam Tips
5 expert strategies to help you pass the FE Chemical Exam
Master Material and Energy Balance Calculations
Material and energy balances form the backbone of chemical engineering and appear throughout the FE Chemical exam. Practice setting up balance equations for systems with recycle streams, purge streams, and bypass streams. Always define your system boundary clearly before writing any equations.
Know Phase Equilibrium and VLE Diagrams
Vapor-liquid equilibrium (VLE) questions test your understanding of Raoult's law, Henry's law, and activity coefficients. Practice reading T-x-y and P-x-y diagrams and performing bubble point and dew point calculations. These problems are formula-driven and become reliable points with practice.
Review Chemical Reaction Kinetics Thoroughly
Understand the difference between zero-order, first-order, and second-order reactions and how to determine reaction order from experimental data. Practice designing ideal reactors (CSTR, PFR, batch) and know when each type is preferred. Pay attention to residence time and conversion calculations.
Focus on Thermodynamics Property Calculations
Be comfortable calculating enthalpy, entropy, and Gibbs free energy changes for chemical processes. Know how to use steam tables and ideal gas relations from the reference handbook. Practice applying the first and second laws of thermodynamics to open and closed systems.
Practice Process Control Fundamentals
Process control questions cover transfer functions, block diagrams, and PID controller tuning. Practice reducing block diagrams to find overall transfer functions. Understand stability criteria including the Routh array method. These problems follow predictable patterns once you learn the techniques.
