Across
- 4. A+B-> AB
- 6. it is very hard, not impossible, to reverse
- 8. AB+CD-> AD+CB
- 9. If changed the equilibrium shifts to oppose change, until new or equilibrium is reached.
- 11. energy transfers from reactants to surroundings (exo- exit)
- 14. must be added to break bonds
- 15. Change the rate of chemical reactions
Down
- 1. AB+C-> AC+B
- 2. the energy stored in molecules that can be released during a reaction
- 3. when reaction and its reverse act at the same rate.
- 5. a substance that is the result of the chemical change
- 7. energy is transferred to reactants from surroundings
- 10. a substance that undergoes a chemical change
- 12. when a solid material forms from a chemical change
- 13. AB-> A+B
