Irreversible Reactions and Reversible Reactions and Changes with Examples in Chemistry

Irreversible Reactions

1. These reactions proceeds to completion in a definite direction and reactants are completely changed into products.
2. These reactions proceed only in the forward direction.
3. These reactions are shown by the single-headed arrow.
4. Combustion and precipitation reactions’ are irreversible reactions.

Reversible Reactions

1. These reactions never proceed to completion and some amount of reactants, small or large, always remain unreacted.
2. These reactions proceed in both forward and reverse directions.
3. These reactions are shown by the double-headed arrow.
4. Esterification and formation of the Ammonia by Haber’s process are Reversible Reactions.
