A reversible reaction is a reaction in which the conversion of reactants to products and the conversion of products to reactants occur simultaneously. One example of a reversible reaction is the reaction of hydrogen gas and iodine vapor to from hydrogen iodide.A reversible reaction is a reaction in which the conversion of reactants to products and the conversion of products to reactants occur simultaneously.

What are 4 examples of reversible reactions?
A reversible reaction. Bunsen burner heats a bowl of hydrated copper(II) sulfate. Water is driven off, leaving anhydrous copper(II) sulfate. The burner is turned off and water is added using a pipette. The bowl now contains hydrated copper(II) sulfate again.
Is an example of a change that can be reversed?
Examples of reversible changes Melting: Melting is when solid converts into a liquid after heating. Example of melting is turning of ice into water. Example of freezing is turning of water into ice. Boiling: Boiling is when a liquid converts into a gas.

What are reversible and irreversible changes class 6?
Reversible changes: The changes which can be brought back to its original form are known as reversible changes. For example, melting of wax and stretching of a rubber band. Irreversible changes: The changes in which the matter cannot be brought back to its original state are known as irreversible changes.
What is the difference between a physical change and a chemical change?
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed.
What is a reversible chemical reaction?
A reversible chemical reaction is one in which the products, as soon as they are formed, react to produce the original reactants. At equilibrium, the two opposing reactions go on at equal rates, or velocities, and hence there is no net change in the amounts of substances involved.
Which of these is a physical and irreversible change?
When a paper is torn, the size and the shape of the paper changes, but the molecules of the paper remains the same. Since, no new molecules are formed, tearing paper is a physical change. At the same time, we cannot get back the sheet of paper from the pieces. Thus, the physical change is irreversible.
What are the examples of reversible and irreversible changes?
The freezing of ice and the melting of wax are examples of reversible change. Irreversible Change–A change that cannot be reversed is called an irreversible change. The burning of wood and rusting of iron are examples of irreversible change. Explore more such questions and answers at BYJU’S.
What are two examples of physical changes?
Changes in the size or form of matter are examples of physical change. Physical changes include transitions from one state to another, such as from solid to liquid or liquid to gas. Cutting, bending, dissolving, freezing, boiling, and melting are some of the processes that create physical changes.
What’s the opposite of reversible?

Which is the best example of a change that can be undone?
Reversible changes are changes that can be undone or reversed. Melting, freezing, boiling, evaporating, condensing, dissolving and also, changing the shape of a substance are examples of reversible changes.
Which of these is an irreversible change?
