Question Twenty Three

• What three things are necessary for a successful
  reaction to occur?
• Reactant molecules must collide
• The collision must occur with sufficient energy
  to get over the activation energy hump
• The collision must occur with the proper
  orientation

28
Question Twenty Four

• What are four ways to speed up a reaction?
• Increase concentration
• Increase temperature
• Increase pressure of a gaseous system
• Add a catalyst
• More Surface Area

29
Question Twenty Five

• How does increasing the temperature increase
  reaction rate?
• Molecules have more energy and therefore there
  will be more collisions and the increased energy
  means a greater fraction of the molecules will
  have enough energy to get over the activation
  energy hump

30
Question Twenty Six

• What is entropy?
• A measure of the disorder in a system

31
Question Twenty Seven

• How does adding a catalyst affect the reaction
  rate?
• It speeds up a reaction by lowering the
  activation energy so that more molecules have
  sufficient energy to get over the activation
  energy.

32
Question Twenty Eight

• Which has more entropy, solid water or water
  vapor? Why?
• Water vapor has more entropy because there is
  more disorder in the gaseous state than in the
  solid state due to the increased molecular motion
  of gases
