ChE Board study guide

ChE Board · Work through your exam, one topic at a time.

The Chemical Engineer licensure examination is one of the licensure examinations administered by the Professional Regulation Commission (PRC) of the Philippines for regulated professions. Passing it is the route to registration as a Chemical Engineer and to a Professional Identification Card (PIC) and Certificate of Registration (COR) issued through PRC. This page is an independent study resource for candidates preparing for that examination; it is not affiliated with, endorsed by, or connected to the PRC or its Professional Regulatory Board. The PRC's own site is the authoritative source for requirements, schedules, and procedures, and it lists www.prc.gov.ph, online.prc.gov.ph, cpdas.prc.gov.ph, crms.prc.gov.ph and its official Facebook page as its only official channels; other sites and pages using the PRC name or logo are unauthorized. Candidates should treat exam-day details - schedule, testing mode, covered subjects, and passing rules - as things to confirm against PRC issuances rather than assume. Preparation should be built around the core chemical engineering disciplines and sustained problem-solving practice, using the PRC Citizen's Charter for documentary requirements and timelines. Topics on this exam: Chemical Engineering. The ChE Board study guide has 1 section and about 418 words.

Chemical Engineering

This domain checks whether you can set up and solve process problems from first principles: material and energy balances, phase and chemical equilibrium, reaction kinetics and reactor sizing, and the unit-operation correlations used in fluid flow, heat transfer, and mass transfer. Most items are numerical, so marks come from choosing a correct basis and carrying units cleanly. Write balances in moles unless the problem is explicitly mass-based; mole balances preserve stoichiometry. Identify the limiting reactant by dividing each feed by its stoichiometric coefficient; do not compare raw molar amounts.

  • Practice questionsFor an ideal gas flowing through a well-insulated horizontal nozzle at steady state, which quantity remains constant along the flow?
  • FlashcardsExtent of reaction. A single variable that tracks how far a reaction has proceeded; species moles equal initial moles plus stoichiometric coefficient times extent, and one extent exists per independent reaction.
  • Cheat sheetMaterial balance on a steady-state unit: Σ(mass in) = Σ(mass out) + accumulation; set accumulation to zero unless the problem states holdup changes, and count each chemical species separately when reactions occur.
  • Key termsUnit operation. A single physical or chemical processing step, such as distillation, filtration, or drying, that transforms material without changing its chemical identity.
  • Study planBuild a one-page formula sheet covering material balances, ideal-gas and phase-equilibrium relations, and unit conversions, then solve 20 mixed stoichiometry and recycle/purge problems without notes.
  • Common mistakesCandidates read the problem statement quickly, see percentages, and default to whichever basis they used last.
