Problem 2PE

Calculating Equilibrium Concentrations from Initial Concentrations

A 1.000-L flask is filled with 1.000 mol of H2(g) and 2.000 mol of l2(g) at 448 ℃. The value of the equilibrium constant Kc for the reaction

H2(g) + l2(g) ⇌ 2 Hl(g)

at 448 °C is 50.5. What are the equilibrium concentrations of H2, I2, and HI in moles per liter?

For the equilibrium PCl5(g) ⇌ PCl3(g) + Cl2(g), the equilibrium constant Kp is 0.497 at 500 K. A gas cylinder at 500 K is charged with PCl5(g) at an initial pressure of 1.66 atm. What are the equilibrium pressures of PCl5, PCl3 and Cl2 at this temperature?
