Unformatted text preview: markowitz (am45362) H05: Equilibrium 2 mccord (51625) 1 This printout should have 15 questions. Multiplechoice questions may continue on the next column or page find all choices before answering. 001 10.0 points A 2.000 liter vessel is filled with 4.000 moles of SO 3 and 6.000 moles of O 2 . When the reaction 2 SO 3 (gas) 2 SO 2 (gas) + O 2 (gas) comes to equilibrium a measurement shows that only 1.000 mole of SO 3 remains. How many moles of O 2 are in the vessel at equilib rium? 1. 7.500 mol 2. 7.000 mol 3. 3.750 mol 4. 12.000 mol 5. None of these is correct. 002 10.0 points Suppose the reaction A B has an equilibrium constant of 1.0 and the ini tial concentrations of A and B are 0.5 M and 0.0 M, respectively. Which of the following is the correct value for the final concentration of A? 1. 0.250 M 2. 0.500 M 3. None of these is correct. 4. 1.50 M 5. 1.00 M 003 10.0 points Suppose the reaction H 2 (g) + I 2 (g) 2 HI(g) has an equilibrium constant K c = 49 and the initial concentration of H 2 and I 2 is 0.5 M and HI is 0.0 M. Which of the following is the correct value for the final concentration of HI(g)?...
