Question

What is the equilibrium equation in chemistry? Is it different from the regular equation?

Answer 1

Hint : We know that the equilibrium is a state of rest or balance due to the equal action of opposing forces. It is an equal balance between something. We can connect this with a chemical reaction to arrive at the answer all chemical "equations" (reactions) are reversible, although the energy requirements may be excessive and make the actual event practically impossible.

Complete Step By Step Answer:
Chemical equilibrium refers to the state of a system in which the concentration of the reactant and the concentration of the products do not change with time and the system does not display any further change in properties. The state of chemical equilibrium is achieved by the system when the rate of forward reaction is equal to the rate of the reverse reaction.
The system is said to be in dynamic equilibrium when there is no further change in the concentrations of the reactants and the products due to the equal rates of the forward and backward reactions. Now we can go through the main characteristics of chemical equilibrium:
At equilibrium, the rate of forward reaction is equal to rate of backward reaction.
All the reactants and products are present at chemical equilibrium.
There are some equilibrium concentrations in which the concentrations of the reactants and products reach constant values.
We call the short-hand notation for a chemical reaction an “equation” because it does involve “balancing” both sides and it is thus related to the mathematical equation. However, it is not an equation in the mathematical sense, but a description of the equilibrium conditions of a chemical reaction. “Equilibrium constants”, including pH and solubility are measures of the degree of “completion” or shift of a reaction from one side of the equation to the other.

Note :
Remember that there are mainly two types of equilibrium. One is homogeneous equilibrium and another is heterogeneous equilibrium. In homogeneous equilibrium, the reactants and products are all in the same phase.
