Multiple-choice questions may continue on the next column or page find all choices before answering. 001 10.0 points K c = 0 . 100 at a certain temperature for the reaction PCl 5 (g) PCl 3 (g) + Cl 2 (g) . At equilibrium, [PCl 5 ] = 2.00 M and [PCl 3 ] = [Cl 2 ] = 1.00 M. If suddenly 1.00 M PCl 5 (g), PCl 3 (g), and Cl 2 (g) are added, calculate the equilibrium concentration of PCl 5 (g). 1. 4.35 M correct 2. 2.35 M 3. 0.65 M 4. essentially zero 5. 1.35 M Explanation: 002 10.0 points A 10.0 L vessel contains 0.0015 mole CO 2 and 0.10 mole CO. If a small amount of carbon is added to this vessel and the temperature is raised to 1000 C CO 2 (g) + C(s) 2 CO(g) , will more CO form? The value of K c for this reaction is 1.17 at 1000 C. Assume that the volume of the gas in the vessel is 10.0 L. 1. No, the rate of the reverse reaction will increase to produce more CO 2 ....
