Across
- 3. chemical reaction where the reactants form products that react together to give the reactants back
- 4. relationship that states that in an equilibrium mixture, there exists a condition linking the product and reaction concentrations
- 7. the reactants and the products in the equilibrium mixture are in the same phase
- 8. heat is absorbed by the system from the surroundings
- 12. the speed at which a chemical reaction takes place
- 13. the measurement of energy in a thermodynamic system
- 14. if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change to reestablish an equilibrium
- 17. the substance that is present at the end of a chemical reaction
Down
- 1. releases heat, causing the temperature of the immediate surroundings to rise
- 2. number that expresses the relationship between amounts of products and reactants present at equilibrium
- 5. natural physical system that does not allow for transfer of matter in or out of the system
- 6. the state of the equilibrium in a system that has components in more than one phase
- 9. the state in which both the reactants and products are present in concentrations
- 10. a measure of the relative amounts of products and reactants present in a reaction at a given time
- 11. process combining nitrogen air with hydrogen derived mainly from methane into ammonia
- 15. the minimum amount of extra energy required by a reacting molecule to be converted
- 16. the substances which participate in a chemical reaction
