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.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²
