Across
- 4. the degree or intensity of heat present in a substance or object.
- 6. Chemical kinetics is the description of the rate of a chemical reaction
- 9. the minimum amount of energy needed to begin a chemical reaction
- 10. the energy change in an overall chemical reaction is equal to the sum of the energy
- 11. the speed of the reaction
- 12. Increasing the surface area of a reactant increases the frequency of collisions and increases the reaction rate
- 14. absorbing energy in a reaction
- 15. the movement of one or more components of a mixture to improve contact.
Down
- 1. releasing energy in a reaction
- 2. a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
- 3. a thermodynamic quantity equivalent to the total heat content of a system. It is equal to the internal energy of the system plus the product of pressure and volume.
- 5. a reaction that, depending on ambient conditions, can proceed in either of two directions
- 7. used to relate the free energy changes that occur during the progress of chemical processes
- 8. Forward reaction is a reaction in which products are produced from reactants and it goes from left to right in a reversible reaction.
- 13. something that keeps a chemical reaction from occuring
