Problem: When a liquid is in dynamic equilibrium with its vapor in a closed container:(a) the rate at which molecules from the liquid phase enter the gas phase exactly equals the rate at which molecules from the gas phase pass into the liquid.(b) a change in temperature will not change the pressure in the container.(c) the amount of gas in the container must exactly equal the amount of liquid.(d) molecules cannot go from the liquid phase to the gas phase because the amount of liquid in the container is constant.(e) the vapor will gradually change back to the liquid state, that is, no vapor will be left.

Define dynamic equilibrium and determine what happens when it occurs in a closed container

Dynamic equilibrium is the status of a system in which reciprocal processes (for example, vaporization and condensation) occur at equal rates.

In this case, analyze each statement:

When a liquid is in dynamic equilibrium with its vapor in a closed container:

(a) the rate at which molecules from the liquid phase enter the gas phase exactly equals the rate at which molecules from the gas phase pass into the liquid.

(b) a change in temperature will not change the pressure in the container.

(c) the amount of gas in the container must exactly equal the amount of liquid.

(d) molecules cannot go from the liquid phase to the gas phase because the amount of liquid in the container is constant.

(e) the vapor will gradually change back to the liquid state, that is, no vapor will be left.
