8. What is C.? high temperature, high pressure A 500

9. When the concentration of a reactant is decreased the shift is in this direction B 100

10. What is to the left? B 100

11. Decreasing the temperature of an exothermic reaction will shift the reaction in this direction B 200

12. Consider the reaction FeCl3 + KSCN ⇔ K3[Fe(SCN)6] + 3KCl yellow colorless red colorless Adding more KSCN to the reaction will do this to the color B 300

13. Consider the reaction FeCl3 + KSCN ⇔ K3[Fe(SCN)6] + 3KCl yellow colorless red colorless Adding Fe 3+ion to the reaction will do this to the color B 400

14. When the volume of the container of the following reaction is decreased it increases the concentration of all substances. The substances (all gases) that increase the most when the new equilibrium is reached 4HCl + O2 ⇔ 2Cl2 + 2 H2O B 500
