Rules A scenario will be presented on the board. Move to the side of the room with the corresponding answer you believe is correct. 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.

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

ANSWER K= CO2 / CO2 DOOR

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

SHIFT RIGHT LAB STATIONS ANSWER SHIFT RIGHT LAB STATIONS

SCENARIO THREE C(s)+ CO2 (g) ↔ 2 CO (g) addition of CO2 DOOR: shift left PERIODIC TABLE: remain neutral LAB STATIONS: shift right

ANSWER SHIFT RIGHT LAB STATIONS

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

No Change PERIODIC TABLE ANSWER No Change PERIODIC TABLE

SCENARIO FIVE Which factor doesn’t affect the reaction rate? DOOR: liquids and solids PERIODIC TABLE: concentration and surface area LAB STATIONS: temperature and catalysts

LIQUIDS AND SOLIDS DOOR ANSWER LIQUIDS AND SOLIDS DOOR

SCENARIO SIX Which speeds up a chemical reaction? DOOR: inhibitor PERIODIC TABLE: catalyst

CATALYST PERIODIC TABLE ANSWER CATALYST PERIODIC TABLE

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

ANSWER PRODUCTS DOOR

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

SIDE WITH LESS MOLES DOOR ANSWER SIDE WITH LESS MOLES DOOR

SCENARIO NINE If the energy is on the right side of the equation, is the reaction endothermic or exothermic? PERIODIC TABLE: endothermic LAB STATIONS: exothermic 

EXOTHERMIC LAB STATIONS ANSWER EXOTHERMIC LAB STATIONS

SCENARIO TEN With an increase in concentration, the equilibrium will shift to the opposite side. PERIODIC TABLE: true LAB STATIONS: false

ANSWER TRUE PERIODIC TABLE

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

PRODUCTS OVER REACTANTS LAB STATIONS ANSWER PRODUCTS OVER REACTANTS LAB STATIONS
