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.

This work is an illustration of a theory as it is a well-examined, broadly accepted explanation about the natural world.  

Trautz and Lewis, in their work on collision, illustrated how the chemical reactions take place and why they exhibit distinct rates of reaction. In 1916, Mark Trautz initially proposed his collision theory, while in 1918 William Lewis postulated his collision theory.  

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.
