A 2 4156 g sample of PCl5 was placed in an empty
A 2.4156-g sample of PCl5 was placed in an empty 2.000- L flask and allowed to decompose to PCl3 and Cl2 at 250.0oC:
PCl5(g) ⇌ PCl3(g) + Cl2(g)
At equilibrium the total pressure inside the flask was ob-served to be 358.7 torr.
a. Calculate the partial pressure of each gas at equilibrium and the value of Kp at 250.0oC.
b. What are the new equilibrium pressures if 0.250 mole of Cl2 gas is added to the flask?
