Question

Q3. Differentiate between reversible and irreversible changes? Reversible changes Irreversible changes​

Answer 1

ANSWER :

REVERSIBLE CHANGE : • It is also known as physical change. • No new substance is formed. • No significiant change in energy is involved.

IRREVERSABLE CHANGE : • It is also known as chemical change. • New substances are formed. • Energy is either absorbed or given out during a Irreversable Change.

Answer 2

Reversible changes:

• A process/ reaction that can be reversed so that the original state such as size, shape of the substances can be obtained.

• The process is bidirectional occurs in both direction. Reactants are converted to products and products converted into the reactants.
• The process result in a temporary change.
• Infinite changes occur in the system.
• There is an equilibrium between the initial state and the final state of the system.

Irreversible changes:

• A process/ reaction that cannot be reversed. It is a reaction or change that produces a new substances.
• The process is unidirectional or occurs in one direction only. The products formed cannot be converted back into the reactants.
• The process result in a temporary change.
• Finite changes occur in the system.
• There is no equilibrium in the system.
