Problem 13.25

When pure hydrogen iodide gas enters an evacuated cylinder, the following reactions may occur: 

(Note that since Gibbs energies of formation data are available for iodine in both the gaseous and solid phases, it is more convenient to think of the solid-vapor iodine phase equilibrium as a chemical equilibrium.) If the reaction mixture is gradually compressed at 25°C, a pressure is reached at which the first bit of solid iodine appears. What is the pressure at which this occurs, and what is the vapor composition at this pressure?
