Exercise

Exercise Calculating Equilibrium Pressures:

Hydrogen iodide gas, which can be dissolved in water to form hydriodic acid, is made by passing hydrogen gas and iodine vapor over a platinum catalyst.

H₂(g) + I₂(g) 2HI(g) K_P = 2.3 at 60 C

If enough hydrogen and iodine are added to a container at 60 C to yield initial partial pressures of 1.0 atm for both H₂(g) and I₂(g), what are the equilibrium partial pressures of all of the gases in the container?
