Chemical engineers often need to work with both unit operations and unit processes. Can you tell me, in your own words, the difference between them?

As a chemical engineer, you can expect both technical and operational questions during the interview. This question deals with the differences between two basic aspects of chemical engineering. Most chemical engineers with any training or knowledge of the subject should be able to give some idea of this contrast in their own words. The answer deals with mass, concentration, energy, and reactions.

"Unit operations involve changes that occur such as evaporation or distillation. Unit processes involve chemical reactions such as oxidization or reduction of a compound."
