Skill 15.3 Explaining the dynamic equilibrium between phases 

A dynamic equilibrium consists of two opposing reversible processes that both occur at the same rate. Balance is a synonym for equilibrium. A system at equilibrium is stable it does not change with time. Equilibria are drawn with a double arrow. 

When a process at equilibrium is observed, it often doesn t seem like anything is happening, but at a microscopic scale, two events are taking place that balance each other. Arrows in this diagram represent the movement of molecules. When water is placed in a closed container, the water evaporates until the air in the container is saturated. After this occurs, the water level 

Chemical reactions often do not go to completion. Instead, products are generated from reactants up to a certain point when the reaction no longer seems to occur, leaving some reactant unaltered. At
