Best Answer

In the system at equilibrium liquid water-water vapor, if liquid water is added to the system, more liquid water molecules will change to water vapor until a new equilibrium is reached.

How can the equilibrium be affected?

If a constraint (such as a change in pressure, temperature, or concentration of a reactant) is applied to a system in equilibrium, the equilibrium will shift so as to tend to counteract the effect of the constraint.

Let's consider the following system at equilibrium.

H₂O(l) + heat ⇄ H₂O(g)

Which statement best describes what will happen if liquid water is added to the system?

  • More liquid water molecules will change to water vapor until a new equilibrium is reached. Yes. This will happen to counteract the excess of liquid water.
  • All of the liquid water molecules that are added will become water vapor. No. Some liquid molecules will change to vapor to attain a new equilibrium.
  • More water vapor molecules will change to liquid water until a new equilibrium is reached. No. The change will happen in the inverse sense.
  • All of the liquid water molecules that are added will remain liquid water. No. Some liquid molecules will change to vapor to attain a new equilibrium.

In the system at equilibrium liquid water-water vapor, if liquid water is added to the system, more liquid water molecules will change to water vapor until a new equilibrium is reached.
