Which activity is included in the practice of chemical engineering?

• A. Teaching professional chemical engineering subjects
• B. Chemical analysis
• C. Performing medical diagnoses
• D. Negotiating international trade agreements

Answer: (A)

Teaching professional chemical engineering subjects is included in the practice because chemical engineers not only design and operate processes, but also educate and train others, share knowledge, and help advance the profession. This educational role—whether in classrooms, laboratories, or industry training programs—embodies applying and communicating engineering principles, mentoring new engineers, and upholding professional standards. The other activities fall outside the core scope of chemical engineering practice: medical diagnoses are for healthcare professionals, and negotiating international trade agreements belongs to policy or law, not engineering. While chemical analysis is a common tool used by engineers, teaching the subject directly reflects the professional activity of developing and disseminating engineering knowledge.
