Category 1 200
• Temperature is a measure of.

5
Category 1 400
• What phase change occurs during sublimation?

6
Category 1 600
• Why is the heat of vaporization of water greater
than the heat of fusion?

7
Category 1 800
• What amount of heat energy is absorbed when 50 g
of water is heated from 10C to 20C?

8
Category 1 1000
• Describe section AB and BC. Include as much
detail as possible.

9
• Average kinetic energy

10
• Solid to Gas

11
• The change from liquid to gas requires more
energy.

12
• 2090 J

13
• AB Heat of fusion, MP/BP, PE inc, KE constant
• BC KE inc, PE constant, LIQUID

14
Category 2 200
• A gas is at 300K and 0.25 atm
• How could you make this gas behave more like an
ideal gas?

15
Category 2 400
Compare the number of molecules in two 1.5L
samples of gas at STP.
Daily Double
16
Category 2 600
• A closed 1 L system contains H2 gas. How will an
increase in temperature effect the pressure in
the container.

17
Category 2 800
• Compare the entropy of H2O(g) to H2O(s)

18
Category 2 1000
• Describe an ideal gas according to the Kinetic
Molecular Theory.

19
• Decrease temperature, increase pressure

20
• The number of molecules are the same in both
gases.

21
• The pressure will increase.

22
• The entropy of the gas is higher because gases
are more disordered.

23
1. Particles have random motion
2. No attraction between particles.
3. Particles are small compared to the space between
them.
4. Particles will collide and transfer energy, but
overall, energy is conserved.

24
Category 3 200
• Describe the energy and entropy trends that exist
in nature.

25
Category 3 400
• What 2 conditions describe systems that have
reached equilibrium?

26
Category 3 600
• How does the addition of a catalyst impact the
activation energy and rate of reaction?

27
Category 3 800
• What conditions must be met for an effective
collision between particles to occur?

28
Category 3 1000
• Label A and B and indicate whether this reaction
is endothermic or exothermic?

29
• Systems tend towards high entropy and love energy.

30
1. The system must be closed.
2. There are equal amounts of reactants and
products.

31
• Catalysts decrease activation energy and increase
the rate of reaction.

32
• Proper energy and orientation.

33
• A activation energy of forward reaction.
• B Heat of reaction
• Endothermic

34
Category 4 200
• Define oxidation.

35
Category 4 400
• What is reduction?

36
Category 4 600
• Describe the energy conversion that occurs in
electrolytic and voltaic cells.

37
Category 4 800
• Describe the reaction that occurs at the anode
and cathode of an electrolytic cell.

38
Category 4 1000
• This equation describes a reaction at
equilibrium.
• For the forward reaction
• Which substance oxidized?
• Which substance is reduced?

39
• LEO when an atom loses electrons!

40
• GER when an atom gains electrons.

41
• Electrical energy is converted to chemical energy.

42
• Oxidation occurs at the anode.
• Reduction occurs at the cathode.

43
1. Chlorine is reduced.
2. Hydroxide is oxidized.
