Question

What is meant by equilibrium reaction, write its type only and explain Dynamic nature of equilibrium with suitable examples.

Answer 1

Chemical equilibrium is the condition of a chemical reaction in which all the reactants and products are present in quantities that have no further propensity to change over time, resulting in no detectable change in the system's properties.

Complete answer:
Chemical equilibrium is the state of a system in which the concentration of the reactant and the concentration of the compounds do not change with time and the system's properties do not change.

Homogeneous Chemical Equilibrium
The reactants and products of chemical equilibrium are all in the same step in this form. The two forms of homogeneous equilibrium are as follows: The number of molecules in the products equals the number of molecules in the reactants in these reactions. For example,
${{\text{N}}_2}(\;{\text{g}}) + {{\text{O}}_2}(\;{\text{g}}) \rightleftharpoons 2{\text{NO}}({\text{g}})$
Heterogeneous Chemical Equilibrium
The reactants and products of chemical equilibrium are present in various phases in this form. Here are a few examples of heterogeneous equilibrium.
${\text{CaC}}{{\text{O}}_3}(\;{\text{s}}) \rightleftharpoons {\text{CaO}}({\text{s}}) + {\text{C}}{{\text{O}}_2}(\;{\text{g}})$

Dynamic Equilibrium
Once a reversible reaction happens, a complex equilibrium exists in chemistry and physics. There is no net difference because substances migrate at the same rate between reactants and drugs. The rate at which reactants and products are produced is such that none of their concentrations varies. It is an example of a mechanism that is in a stable state. When reactions occur at such frequencies that the structure of the mixture does not vary over time, a closed system is said to be in thermodynamic equilibrium. Reactions do happen, often violently, but not to the point where differences in composition can be seen.

Note:
By setting the chemical potentials of carbon dioxide in the two phases to be equal, Henry's law can be derived. Chemical equilibrium is described by chemical potential equality. Partition coefficient and solubility product are two other constants for complex equilibrium involving phase shifts. The equilibrium vapour pressure of an ideal solution is defined by Raoult's law.
