Reversible reactions are those where the products are in equilibrium at a set of conditions. For one of the most simple examples to illustrate this, look at ice water. At equilibrium conditions, a class of ice water is half ice and half water. If you shift the conditions by heating the ice water, ice will melt to bring the temperature back to equilibrium conditions but the ratio of ice to water will have changed.
can the reaction between alkali and acid be reversed
You think probable to a reversible reaction.
A non-reversible reaction is a chemical reaction in which the products cannot readily revert back to the original reactants. This means that once the reaction has occurred, it is not easily undone under normal conditions. Examples include combustion reactions and many precipitation reactions.
Dissecting a banana is a physical change, not a chemical reaction. It involves physically separating the banana into smaller pieces, but the chemical composition of the banana doesn't change. A reversible change would be when you freeze the banana slices and then thaw them, as this can be reversed.
Burning of a cracker is an irreversible change. Once the cracker is burnt, it undergoes a chemical reaction that cannot be easily reversed to its original form.
no it is not reversible because a chemical reaction has taken place that cannot be reversed.

You think probable to a reversible reaction.
Chemical changes cannot be reversed because they involve the formation of new substances with different chemical properties. Once a chemical reaction occurs, it is usually not possible to return the reactants to their original state.
An irreversible reaction is a chemical reaction that proceeds in one direction only, meaning it cannot be easily reversed. In contrast, a reversible reaction is a chemical reaction that can proceed in both forward and reverse directions, reaching a state of equilibrium where the rates of the forward and reverse reactions are equal.
A non-reversible reaction is a chemical reaction in which the products cannot readily revert back to the original reactants. This means that once the reaction has occurred, it is not easily undone under normal conditions. Examples include combustion reactions and many precipitation reactions.
Burning is not reversible because it involves a chemical reaction that permanently changes the substances involved. Heating, on the other hand, is reversible since it involves providing energy to increase the temperature but can be reversed by removing the heat.
Most sterilization is reversible.
An anabolic reaction is considered reversible.

The decomposition of calcium carbonate is reversible as it can be reversed by recombining calcium oxide and carbon dioxide to form calcium carbonate again through a chemical process known as carbonation.
