__________________________ Name: Date: _____________ Version B Part 1. Calculation/Short Answer Problems. All work for the following problems must be done in THIS TEST BOOKLET to receive credit. Calculations done with no work will receive zero points. You work must be clear and logical AND SHOWN to receive maximum (or any) credit. A. For the reaction: SO2Cl2(g) SO2(g) + Cl2(g) at 375 K, the equilibrium constant KP is 2.40. In an experiment, a sample of pure SO2Cl2 gas is placed in a sealed reaction vessel. The initial pressure of SO2Cl2 is 5.00 atm. The reaction is allowed to come to equilibrium. What are the final equilibrium pressures of all the gases? You must set up and use an equilibrium table. (Hint: the quadratic equation is needed.)
