A constant volume container holds an equilibrium mixture of Cl2(g), PCl3(g), and PCl5(g) gases, which have partial pressures of 2.7, 2.7, and 9.1 torr, respectively. An amount of Cl2(g) is quickly injected into the container until the total pressure reaches 20 torr, and then the total pressure in the container is measured as the system relaxes back to equilibrium. Answer the following questions about this system:

a. What is the balanced chemical reaction for this equilibrium system and the numerical value of the corresponding equilibrium constant?

b. Sketch a diagram of the total pressure in the container as a function of time, starting before the additional Cl2(g) was injected until equilibrium is again achieved.

c. Sketch a diagram showing the partial pressures of Cl2(g) and PCl3(g) as functions of time.

d. Calculate the partial pressures of the three gases after the system has relaxed back to equilibrium. Selected Answers: 1a: Grams(butane) = 1.52gr. Grams(hexane) = 1.03gr. 3: 919.2 kg of H2SO4 5: 70kJ. 6b: 1.64 atm 7b: 18.55 torr.
