Are evaporation and condensation opposite to each other and equilibrium be achieved between water and its vapour?
You have asked three questions, which are actually one question in different wording. I've answered to one of your posts.
Opposite process of evaporation is condensation. During condensation, liquid water is formed from water vapour by cooling. Condensation is the change of the physical state of matter from the gaseous phase into its liquid phase, and is the reverse process of vaporization. The opposite of evaporation is condensation. While evaporation is the process of liquid changing into a gas, condensation is the process of a gas changing into a liquid. Evaporation and condensation are two processes through which matter changes from one state to another. Matter can exist in three different states: solid, liquid or gas. In evaporation, matter changes from a liquid to a gas. In condensation, matter changes from a gas to a liquid. Condensation of a vapour to form a liquid or a solid is the reverse of vaporization and in the process heat must be transferred from the condensing vapour to the surroundings. The amount of this heat is characteristic of the substance, and it is numerically the same as the heat of vaporization. The equilibrium between water and its vapour in an open vessel cannot be achieved because the water molecules are continuously evaporating and condensing due to the absence of any barrier to prevent them from escaping into the air. Equilibrium has been established between a liquid and its vapor when c. the liquid reaches its boiling point. At this point, the forward and reverse reactions from liquid to gas will equal one another, and the concentrations of either will not change no matter what the initial concentrations are. The dissociation of water is an equilibrium reaction. It means the rate of the forward reaction is equal to the rate of the reverse reaction and the concentration of the reactants and products do not change at equilibrium.Equilibrium can be achieved when the opposing processes evaporation and condensation occur simultaneously. But in an open vessel the rate of evaporation will never become equal to the rate of condensation.
All your posts are very long, sometimes confusing and even wrong. All what you have written looks like teaching of basics of physics on very low level. There is nothing to discuss. Sorry for a straightforward language.
