Chemical Equilibrium

Chemical equilibrium can be defined as the state where there is no observable change in the properties of a system with respect to time. Studies have shown that some reactions are such that all the reactants are never completely converted into products.

In such reactions, the products when formed are converted to reactants. Such reactions are said to be reversible. A reversible reaction is one that proceeds in both directions under suitable conditions.

Many natural processes are reversible.

1. Atmospheric oxygen is produced by photosynthesisPhotosynthesis is the process by which green plants, and some algae and bacteria, convert the energy of sunlight into chemical energy. This energy is then used to synthesize carbohydrates such as... More in plants, while plants and animals consume oxygen during photosynthesis.
