During an experiment, solid iodine was placed in a sealed container. The container was gradually heated and purple-colored vapors of iodine formed were observed. Describe this system when it reaches phase equilibrium. (10 points)

See explanation

Explanation:

When you heat solid iodine, the following equilibrium is set up;

I2(s) ⇄I2(g)

Let us recall that at equilibrium, the rate of forward reaction and the rate of reverse reaction become equal.

This means that the concentration of the solid iodine and iodine vapour becomes fairly stable because the rate at which the solid is converted to vapour equals the rate at which the vapour is converted to solid.

some of the qualities most frequently associated with the baroque are grandeur, sensuous richness, drama, vitality, movement, tension, emotional exuberance, and a tendency to blur distinctions between the various arts.
