Chemical Equilibrium

Science

A state in which the rate of the forward reaction equals the rate of the backward reaction

Chemical equilibrium

A state in which the rate of the forward reaction equals the rate of the backward reaction. Chemical equilibrium. Chemical equilibrium is when a chemical reaction has balanced out so that its products and reactants remain constant over time.

An ion that is in common to both salts in a solution

Common ion

An ion that is in common to both salts in a solution. Common ion. In Science, a common ion is an ion found in both compounds in a mixture, affecting solubility and chemical equilibrium.

The lowering of solubility by the presence of a common ion

Common ion effect

The lowering of solubility by the presence of a common ion. Common ion effect. The common ion effect occurs when a compound's solubility decreases due to the presence of another compound that shares a common ion in solution.

A number that expresses the relationship between the amounts of products and reactants

Equilibrium constant

A number that expresses the relationship between the amounts of products and reactants. Equilibrium constant. The equilibrium constant is a number that shows the ratio of concentrations of products to reactants at equilibrium in a chemical reaction.

The point in a chemical reaction at which the reactants and products are no longer changing

Equilibrium position

The point in a chemical reaction at which the reactants and products are no longer changing equilibrium position. Equilibrium position is the state in a reaction where the amounts of reactants and products stay constant over time.

Equilibrium condition for a reaction in which all the reactants and products are in two or more different states, (solid, liquid, or gas)

Heterogeneous equilibrium

Equilibrium condition for a reaction in which all the reactants and products are in two or more different states, solid, liquid, or gas. Heterogeneous equilibrium. Heterogeneous equilibrium is when substances in different states, like solids, liquids, and gases, reach a balance in a chemical reaction.

An equilibrium condition for a reaction in which the reactants and products are in the same state, (solid, liquid, or gas)

Homogeneous equilibrium

An equilibrium condition for a reaction in which the reactants and products are in the same state, solid, liquid, or gas. Homogeneous equilibrium. It occurs when substances in a chemical reaction are all in the same physical state.

When a chemical reaction is at equilibrium, the concentration of the reactants and the products remains the same over time

Law of chemical equilibrium

When a chemical reaction is at equilibrium, the concentration of the reactants and the products remains the same over time. Law of chemical equilibrium. It means that at equilibrium, the rates of the forward and reverse reactions are equal, keeping concentrations constant.

It is natural tendency of systems to move in the direction of maximum chaos or disorder

Law of disorder

It is natural tendency of systems to move in the direction of maximum chaos or disorder. Law of disorder. In Science, the law of disorder, or the second law of thermodynamics, means that systems naturally progress towards greater randomness and less order over time.

If stress is applied to a system at equilibrium, the system shifts to relieve the stress

Le Chateliers principle

If stress is applied to a system at equilibrium, the system shifts to relieve the stress. Le Chatelier's principle. This principle explains that when a change occurs in a system at equilibrium, it will adjust to counteract that change and restore balance.

A reaction where the reactants form products, which react together to give the reactants back

Reversible reaction

A reaction where the reactants form products, which react together to give the reactants back. Reversible reaction. In Science, a reversible reaction is a chemical process where products can re-form the original reactants.

Is the equilibrium constant for a solid substance dissolving in an aqueous solution or (Ksp)

Solubility product constant

Is the equilibrium constant for a solid substance dissolving in an aqueous solution or Ksp. Solubility product constant. It measures how much of a solid can dissolve in water before the solution becomes saturated.
