There are few interrelations or unit conversions in this section that are covered explicitly. For the most part, mastering the skills required to solve these types of problems involves repetition; solving many problems until you become comfortable moving from one concept to another smoothly. Some points to keep in mind are listed below:
- How to draw a flow chart when you are given a problem statement
- How to draw boundaries around systems for multi-unit processes
- How to set up a table to solve problems, and how to write equations for each boundary
- For reactions, how to write extents of reactions for each component that goes into or leaves the reactor
- For a reaction (or several reactions), be comfortable with the following definitions (interrelationships): limiting reagents, fractional or percent excess, fractional or percent conversion, selectivity, and yield
- And of course, we need to be ready to choose a basis if we are asked for an answer that is a ratio.
- And lastly, be comfortable with scaling your answers
