Solution

Difference between reversible and irreversible changes:

Serial number Irreversible change Reversible change
1 A change is called irreversible if it cannot be changed back again. A reversible change is a change that can be reversed.
2 For example, you cannot change a cake back into its ingredients again. For example, melted chocolate can be changed back into solid chocolate by cooling.
3 Irreversible changes are permanent. They cannot be undone.
For example, combustion cannot be undone. Reversible changes are not permanent. They can be undone.
For example, we can freeze orange juice to make ice lollies. The ice lollies can be changed back into orange juice by heating.
4 In an irreversible reaction, the reactants react to form the products, which cannot revert back into reactants In reversible reactions, as the reactants react with other reactants to form products, the products are reacting with other products to form reactants.
