4. collision
5. A reaction where the products are lower in energy than the reactants is an example of an _____. (Outcome # 6) (DOK 1)
6. endothermic process
7. exothermic process
8. endergonic process
9. A reaction where the products are higher in energy than the reactants is an example of an _____. (Outcome # 6) (DOK 1)
10. endothermic process
11. exothermic process
12. exergonic process
13. Which of the following affects the rate of a reaction? (Outcome # 6) (DOK 1)
14. concentration, temperature, nature of reactants, presence of solvents
15. concentration, temperature, molecular size, presence of catalysts
16. concentration, temperature, nature of reactants, presence of catalysts
17. What affect does temperature have on the rate of a reaction? (Outcome # 6) (DOK 2)
18. the lower the temperature, the lower the kinetic energy which results in more effective collisions therefore increasing the rate of a reaction
19. the higher the temperature, the greater the kinetic energy which results in more effective collisions therefore increasing the rate of a reaction
20. the higher the temperature, the greater the kinetic energy which results in more effective collisions therefore decreasing the rate of a reaction
21. Which statement best describes the effect of concentration on the rate of a reaction? (Outcome # 6) (DOK 2)
22. higher concentrations result in more effective collisions therefore increasing the rate of a reaction
23. higher concentrations result in less effective collisions therefore increasing the rate of a reaction
24. higher concentrations result in more collisions therefore increasing the rate of a reaction

38. rate = k[A]
39. rate = k[A][B]
40. rate = k[B]
