Chemical reactions occur because bonds between atoms are broken or formed. When atoms or molecules join together, they form new substances called compounds. These compounds can then undergo further chemical reactions.
Reactions can be classified according to whether they are reversible or irreversible. Let’s understand the difference between the two.
Difference between reversible and irreversible reactions:
Reversible reactions are those in which the chemical composition of the reactants does not change and can return to their original forms.
An example would be the reaction between water and vinegar. The two reactants convert to each other, but remain the same chemical compounds.
On the contrary, irreversible reactions give rise to changes in the structure or composition of the reactants. For example, the transformation of milk into curd is an irreversible reaction, since curd cannot be converted back into milk in its original state.

|
It is a long process that includes several minor stages and keeps the environment and the system in balance. |
The process moves quite quickly. Here the system and its environment are not kept in balance. |
|
The reaction is reversible. |
The reaction is irreversible. |
|
The reaction occurs in two directions. |
The reaction occurs in one direction. |
|
There are no chemical changes in the composition of the reactants. |
Chemical changes in the composition of the reactants. |
|
Most physical reactions are reversible. |
Chemical changes are irreversible. |
|
The reactants form products that can return to their original form. |
Reagents form products that can never return to their original form. |
|
Example, NH4Cl(s) ⇌ NH3(g) + HCl(g) |
Example, C(s)+O2(g)→CO2(g) |
|
Another example is ice melting and turning into water and water freezing and turning into ice. |
Another example of an irreversible reaction is the burning of paper. |
In summary, reversible chemical reactions are temporary and the reactants can return to their original forms, while irreversible chemical reactions are permanent and when reactants react with other reactants they form products that can never return to their original form. .
