Why do reversible reactions not go to completion?
Usually because the reactants and products all remain in contact. If one of the products can be removed you can sometimes drive the reaction in the desired direction.
What happens in reversible reaction?
Reversible: When reactions are reversible, it means that, it can go both forward and backward. E.g: *A and B react to C and D but in reversible reactions C and D react to or from A and B. *Water can be ice and ice can be water.

Why is aluminum chloride used in large excess in Friedel-Crafts reactions?
To ensure there's enough of it to allow the reaction to go to completion.
Is plaster of Paris and water a reversible change?
Yes, it is because when you melt it, it becomes soft and slimy, and when you freeze it, it will go back to it
Why a reaction needs to take place at equilibrium?
Many chemical reactions, like combustion , go to completion and not to equilibrium. It is normally desirable to give a chemical reaction time to reach equilibrium in order you get the maximum yield of one or more products.
What types of reactions do not go to completion?
the reactions in which value of Qc=Kc
Why the reversible reaction do not go to completion?
Reversible reactions do not go to completion because the reactants are constantly converting into products and vice versa. At equilibrium, the rates of the forward and reverse reactions are equal, resulting in a dynamic state where both reactions continue to occur but at an equal pace. As a result, there will always be some amount of reactants and products present in a reversible reaction system.
What is the difference between a reversible reaction and a reaction that goes to completion?
The reactions in which the products can recombine to form reactants are called reversible reactions. These reactions never go to completion. They are represented by a double arrow between reactants and products.
Why do reversible reactions not go to completion?
Usually because the reactants and products all remain in contact. If one of the products can be removed you can sometimes drive the reaction in the desired direction.
Can a chemical reaction go back to normal?
Yes, reversible chemical reactions exist.
Are oxidation reduction reactions reversible?
Yes, oxidation-reduction reactions are reversible. This means that the reaction can proceed in both directions, depending on the conditions. Oxidation can be reversed by reduction and vice versa by applying the appropriate conditions and reactants.
What type of reaction requires the addition of energy to go to completion?
Endothermic reactions require the addition of energy to go to completion. This means that for the reactants to form products, energy must be absorbed from the surroundings.
Which is reversible dissolving with acid reacting with acid both or neither?
Both processes are reversible. Dissolving a substance involves the solute breaking apart into ions or molecules in the solvent, which can easily reform by removing the solvent. Similarly, acid-base reactions can go in both directions depending on the concentration of reactants and products.

To ensure there's enough of it to allow the reaction to go to completion.
What is the different between a reversible and an irreversible?
reversible means something can go back to how it was. Irreversible means it cannot
Why are equilibrium expressions not written for reactions that go to completion?
Equilibrium expressions cannot be written for complete reactions, because you have to have the forward rate, as well as a reverse rate. Complete reactions do not have reverse rates, because they become complete, and all of the reactants are used up. Complete reactions only produce products, and the products don't produce reactants. word count for answer: 52
