Multiple-choice 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)?...
