... What types of compounds can act as Lewis acids? • Lewis acids generally have an incomplete octet (e.g., BF3). Consider the reaction between NH3 and BF3. This reaction occurs because BF3 has a vacant orbital in its valence shell. It therefore acts as an electron-pair acceptor (a Lewis acid) toward NH ...

... Why do chemists want to know the rate of a reaction? If you are making a product, it is important to know how long the reaction takes to complete, before the product is produced. Rate is a measure of a change that happens over a single unit time. That unit time is most often a second, a minute, or a ...
