The practice of chemical engineering may include the following activities, except this.

• A. None of the above
• B. Equipment design
• C. Preparation of specification
• D. Teaching, lecturing, and reviewing professional chemical engineering subjects

Answer: (A)

The practice of chemical engineering covers a wide range of activities that move from concept to real-world operation, including designing the equipment that will carry out a process, and turning that design into actionable requirements. Equipment design is central: it involves choosing appropriate units, sizing them, and ensuring they meet safety, efficiency, and integration needs within the overall process. Preparation of specifications is the bridge between design and implementation, detailing the exact mechanical, materials, operator, and performance criteria that vendors and operators must follow. Teaching, lecturing, and reviewing professional chemical engineering subjects are also part of the field, since engineers contribute to education, training, and the upkeep of professional standards—whether in academia, industry training programs, or ongoing professional development. Because all three activities can be legitimately part of chemical engineering practice, there isn’t an activity listed that lies outside the scope.
