Remember this is Jeopardy, so where I have written “Answer” this is the prompt the students will see, and where I have “Question” should be the student’s response. To enter your questions and answers, click once on the text on the slide, then highlight and just type over what’s there to replace it. If you hit Delete or Backspace, it sometimes makes the text box disappear. When clicking on the slide to move to the next appropriate slide, be sure you see the hand, not the arrow. (If you put your cursor over a text box, it will be an arrow and WILL NOT take you to the right location.)

5
Why does powdered zinc react faster than a strip of zinc
6
More surface area
7
How would an increase in pressure effect the rate of a reaction
8
Increases
9
If less reactant is added in a reaction what effect will this have on the rate of reaction
10
Decrease
11
Between ionic and covalent compounds which will react faster and why
12
Ionic because they are smaller and less bonds to break and form new compounds
13
How does a catalyst effect a reaction?
14
Provides a new pathway or lowers activation energy
15
Which Letter represents the activation energy of the reaction?
16
A
17
Which letter Represents the energy of the products
18
C
19
Calculate the cchange in heat for the reaction
20
80 kJ
21
What is the activation energy without a catalyst?
22
140kJ
23
Is the following reaction endo or exothermic? Explain your answer
24
Exothermic because the products have less energy than the reactants
25
What type of equilibrium is shown above
H2O (s) H2O (l) What type of equilibrium is shown above
26
Phase equilibrium
27
At what temperature will this phase equilibrium occur
H2O (s) H2O (l) At what temperature will this phase equilibrium occur
28
Zero degrees Celsius
29
What type of solution needs to be present in order to have equilibrium
30
Saturated
31
Compared to the amount of product made the amount of reactant made during equilibrium is….
32
The same
33
In chemical equilibrium if 3 moles of products are produced how many moles of reactant are produced
34
3 moles
35
4NH3(g) + SO2(g) 4NO(g) + 6H2O(g)+ heat
In the reaction above if H2O is added to the system which way will it shift
36
Left
37
If heat is added to the system which way will it shift?
4NH3(g) + SO2(g)4NO(g) + 6H2O(g)+heat If heat is added to the system which way will it shift?
38
Left
39
4NH3(g) + SO2(g)4NO(g) + 6H2O(g)+heat
If the pressure was decreased in the system which way would the reaction shift?
40
Right
41
4NH3(g) + SO2(g)4NO(g) + 6H2O(g)+heat
If the concentration of SO2 was increased which way would the reaction shift?
42
right
43
How could more product be produced
X + Y Z + heat How could more product be produced
44
Increase concentration of x or y, decrease the heat used
45
Nature tends to move towards what type of entropy
46
high
47
Nature moves towards what type of enthalpy
48
Low
49
Which type of reaction will happen more readily exo or endo?
Explain
50
Exo releases heat lower enthalpy
51
Gas moves from high concentration to lower concentration explain why?
52
To create more entropy (randomness)
53
What conditions must be present for a reaction to happen spontaneously
54
Exothermic and high entropy
55
Final Jeopardy Make your wager
56
Write the equilibrium equation for the following reaction
H2(g) + F2(g) 2HF(g)
57
Keq=[HF]2/[H2]x[F2]
