3. a catalyst that exists in the same physical state as the reaction it catalyzes
4. The mathematical relationship between the rate of a chemical reaction at a given temperature
8. for a reactant describes how the rate is affected by the concentration of that reactant
9. Term used to describe an activated complex because the activated complex is as likely to form reactants as it is to form
11. a short-lived, unstable arrangement of atoms that may break apart and re-form
12. The slowest elementary step in a complex reaction
13. a substance that slows down the reaction rate of a chemical reaction or prevents a chemical reaction from happening
15. a substance produced in one elementary step of a complex reaction
16. states that atoms, ions, and molecules must collide in order to react
17. a chemical reaction that consists of two or more elementary steps

1. a substance that increases the rate of a chemical reaction by lowering activation energies
2. determines the reaction order by comparing the initial rates of a reaction carried out with varying reactant concentrations
4. The change in concentration of a reactant or product per unit time
5. a catalyst that exists in a different physical state than the reaction it catalyzes
6. the rate of decomposition at a specific time
7. The complete sequence of elementary steps that make up a complex reaction
10. the minimum amount of energy required by reacting particles in order to form the activated complex
14. A numerical value that relates reaction rate and concentration of reactant at a specific temperature
