Reaction Kinetics

3. An intermediate molecule which occurs when reactants are in the process of rearranging to form products
6. The energy which a system possesses because of movement within the system
7. A reaction which absorbs heat, so that products have more energy than reactants
9. A reaction which gives off heat, so that products have less energy than reactants
10. Step The slowest step in a reaction mechanism
11. The total kinetic and potential energy which exists in a system when it is at constant pressure
12. The energy existing as a result of an object's position in space
13. A reaction in which all the reactants are in the same phase

1. A chemical which can be added to a reaction to increase the rate of the reaction
2. The amount of a reactant or product involved in a reaction in a specific time
3. The minimum potential energy required to change reactants into an activated complex
4. A chemical which reduces a reaction rate by combining with a catalyst or one of the reactants in such a way as to prevent the reaction from occurring
5. The theory stating that molecules act as small, hard spheres which bounce off each other and transfer energy among themselves during their collisions
8. A reaction in which the reactants are present in different phases
