- 2. the energy which a system possesses because of movement within the system.
- 6. the substances being combined in a reaction.
- 7. an intermediate molecule which occurs when reactants are in the process of rearranging to form products.
- 10. the minimum potential energy required to change reactants into an activated complex.
- 12. a graph showing how the number of particles having a given kinetic energy changes with increasing temperature.
- 13. a chemical which can be added to a reaction to increase the rate of the reaction.
- 14. the energy existing as a result of an object's position in space, as well as the sum of all the attractive and repulsive forces existing among the particles which make up the object.
Down
- 1. the amount of a reactant or product involved in reaction in a specific time.
- 3. the slowest step in a reaction mechanism.
- 4. a reaction which absorbs heat, so that products have more energy than reactants.
- 5. molecules which are produced in one step of a reaction mechanism and subsequently used up in another step.
- 8. the theory stating that molecules act as small, hard spheres which bounce off each other and transfer energy among themselves during their collisions.
- 9. the actual sequence of steps which make up an overall reaction.
- 11. the total kinetic and potential energy which exists in a system when it is at constant pressure.
