For each question you have answered correctly, you will receive a pink slip of paper.
Whoever has the most pieces of paper by the end of the game wins.

3. SCENARIO ONE
Given the reaction C(s)+ CO2 (g) ↔ 2 CO (g) what is the equilibrium expression?
DOOR: K= CO2 / CO2
PERIODIC TABLE: K= (C)(CO2) / (CO2)
LAB STATIONS: K= C+CO2/ 2CO

4. ANSWER
K= CO2 / CO2
DOOR

5. SCENARIO TWO DOOR: shift left PERIODIC TABLE: remain neutral
Given the same reaction     C(s)+ CO2  (g) ↔ 2 CO (g)     how would the system respond if the volume of the container were increased?
DOOR: shift left
PERIODIC TABLE: remain neutral
LAB STATIONS: shift right

6. SHIFT RIGHT LAB STATIONS
ANSWER
SHIFT RIGHT LAB STATIONS

7. SCENARIO THREE C(s)+ CO2 (g) ↔ 2 CO (g) addition of CO2
DOOR: shift left

9. SCENARIO FOUR C(s)+ CO2 (g) ↔ 2 CO (g) addition of He(g)
DOOR: shift left
PERIODIC TABLE: no change
LAB STATIONS: shift right

10. No Change PERIODIC TABLE
ANSWER
No Change PERIODIC TABLE

11. SCENARIO FIVE Which factor doesn’t affect the reaction rate?

15. SCENARIO SEVEN
If K>1 will the equilibrium favor the products or reactants?
DOOR: products
PERIODIC TABLE: reactants

16. ANSWER
PRODUCTS DOOR

17. SCENARIO EIGHT
With a decrease in volume, which side will the equilibrium shift?
DOOR: side with less moles
PERIODIC TABLE: remain
LAB STATIONS: side with more moles

18. SIDE WITH LESS MOLES DOOR
ANSWER
SIDE WITH LESS MOLES DOOR

LAB STATIONS: false

22. ANSWER
TRUE PERIODIC TABLE

23. SCENARIO ELEVEN The equilibrium constant is a ratio of...
DOOR: solids over liquids
PERIODIC TABLE: reactants over products
LAB STATIONS: products over reactants

24. PRODUCTS OVER REACTANTS LAB STATIONS
