7. Sulfuryl chloride, SO2Cl2, is a highly reactive gaseous compound. When heated, it decomposes as follows: SO2Cl2 (g) ⇌ SO2 (g) + Cl2 (g). This decomposition is endothermic. A sample of 3.509 grams of SO2Cl2 is placed in an evacuated 1.00-L bulb and the temperature is raised to 375 K. a. What would be the pressure (in atm) in the bulb if no dissociation of the SO2Cl2(g) occurred? b. When the system has come to equilibrium at 375 K, the total pressure in the bulb is found to be 1.43 atm. Calculate the partial pressures of SO2, Cl2, and SO2Cl2 at equilibrium. c. Give the expression for the equilibrium constant (either Kp or KC) for the decomposition of SO2Cl2(g) at 375 K. Calculate the value of the equilibrium constant you have selected.
