Definition of Equilibrium in Chemistry

Definition of Equilibrium in ChemistryIn a broader sense, the definition of equilibrium may be considered as what an organism would do under given conditions to keep its internal structure in place. For example, let us take the study of living organisms for an example. You will realize that an organism cannot go without food and water; it is the biological needs, which is the ultimate source of regulation and food and water have to be supplied in the necessary quantities and sometimes even in the right proportions.The fundamental law of biology is that there is a balance between the chemical interactions among the body's organs and the environment. As we all know, there are many chemical reactions in the body, and these chemical reactions influence the blood, the nervous system, the functions of the organs and so on.This rule can be generalized to the other aspects of life, or to the rule of cause and effect. It is the same with most of the laws governing the world around us. If you understand the nature of equilibrium, you will understand the law of causality, which is also known as the law of least action.According to this principle, there is no physical or chemical action that will not cause some change in the state of affairs. This change can either be positive or negative, but in general, it is never in the same direction.This law has a couple of interesting effects. You will realize that the inertia of some solid substances may be used as a constant factor in the determination of their weight and size. In the same way, another effect of this law can be found in the behavior of molecules, as there is a tendency for the remaining molecules to combine to form other molecules of smaller sizes than the first ones.Equilibrium is also important in the study of the workings of the weather. There is an interaction of the air, the wind and the ocean, with the result that the air in one part of the globe tends to cool down and the same with the other parts of the gl obe, and this cooling is compensated by the heating of the air in the other parts of the globe. The relation between the temperature of the atmosphere and the altitude above sea level is said to be the thermodynamic equilibrium.According to this, the body becomes active when its surroundings cool down. To be more precise, the natural equilibrium is established in the case of the body that contains the same number of electrons as the number of hydrogen atoms in the atoms. Of course, some organisms have excess hydrogen atoms, because they are difficult to evolve into chemical compounds, because these organisms contain no chemicals and thus cannot combine.
