In their work on collision, Trautz and Lewis explained how chemical reactions occur and why they have different reaction rates. This work is an example of a theory because it is a well-tested, widely accepted explanation about the natural world. a law because it is a statement about how something behaves or functions in the natural world. an explanation because it describes the characteristics of something in the natural world. a hypothesis because it is a possible answer to a scientific question about the natural world.
