More liquid water molecules will change to water vapor until a new equilibrium is reached.

All of the liquid water molecules that are added will become water vapor.

More liquid water molecules will change to water vapor until a new equilibrium is reached.

Reason: Adding reactant shifts the equilibrium to the right (Le Chatelier’s principle) so some of the added liquid will evaporate until the vapor pressure at 100°C is reestablished.
