Le Chatelier's Principle Quiz A Match the change to the equilibrium system below with the letter of the appropriate response. Write your answer on your answer sheet. Each letter can be used once, more than once, or not at all. DO NOT MARK OFF THE ANSWER CHOICES!! 2SO2(g) + O2(g) 2SO3(g) 1. O2 is added to the reaction. a. The equilibrium shifts to the right. 2. SO3 is removed from the reaction. b. The equilibrium shifts to the left. 3. SO3 is added to the reaction. c. There is no change in the equilibrium position. 4. The pressure is increased. If the statement is true, write "true"on your answer sheet. If it is false, change the underlined word or words to make the statement true and write the corrected answer on your answer sheet. NH4Cl(s) + heat NH3(g) + HCl(g) 5. The above reaction is exothermic. 6. The production of ammonia from ammonium chloride will increase at higher temperature. 7. In the above reaction system, the value of Keq decreases as the temperature increases. 8. For the above reaction at equilibrium, an increase in pressure on the system causes a decrease in gaseous ammonia concentration. Answer each of the following questions on your answer sheet. 9. What factors alter the equilibrium position in chemical reactions? 10. Describe Le Chatelier's principle. 11. If more reactant is added to an equilibrium system, what happens to Keq (assume the temperature is not changed)? 12. How is changing the concentration of a reactant in a reaction related to a shift in equilibrium position? 13. For the following reaction, what will occur if pressure is increased? Why? 2NO2(g) N2O4(g) 16. What is the effect of temperature on any equilibrium constant? 17. You are asked to produce HI from H2 and I2. Write the equilibrium expression for this reaction. How would you go about maximizing the amount of HI produced? 18. If the value of Keq is 1.2 x 10-12 for the generalized equation AB (s) A (g) + B (g), what are you likely to see in the reaction vessel at equilibrium?
