Across
- 3. the direction of a reversible reaction is favored
- 4. a series of simple reactions that represent the progress of the overall reaction at the molecular level
- 8. A state of balance
- 10. substance that speeds up the rate of a chemical reaction
- 11. chemical law stating that the rate of a reaction is proportional to the concentration of the reacting substances
- 13. a high-energy intermediate state of the reactants during a chemical reaction that must be achieved for the reaction to proceed
- 17. Energy needed to get a reaction started
- 18. the rate at which reactants change into products over time
Down
- 1. A system in which no matter is allowed to enter or leave
- 2. value that expresses how far the reaction proceeds before reaching equilibrium. A small number means that equilibrium is towards the reactants side while a large number means that the equilibrium is towards the product side
- 5. When a change is experienced by a chemical system in equilibrium, the system will adjust to partially offset the change
- 6. Expression used to determine the unknown equilibrium concentrations. It describes the relationship of the products relative to the reactants in a chemical equilibrium system.
- 7. shows the energy of reactants and products during the course of a reaction
- 9. describes a reaction that involves only one particle that goes on to form products
- 12. a transitional structure that results from an effective collision and that persists while old bonds are breaking and new bonds are forming
- 14. A type of biological protein that speeds up a chemical reaction in a living thing
- 15. the step-by-step sequence of reactions by which the overall chemical change occurs
- 16. an elementary step in a reaction that involves two particles, either the same species or different, that collide and go on to form products
