What is equilibrium in chemistry?
Equilibrium - The state in which the measurable properties of the system such as pressure, density, colour or concentration do not undergo any further noticeable changes with time under a given set of conditions is said to be a state of equilibrium.
- Chemical Equilibrium. In a chemical reaction chemical equilibrium is defined as the state at which there is no further change in concentration of reactants and products.
- Equilibrium in Physical Processes. (i) Solid-Liquid Equilibrium: The equilibrium is represented as. Rate of melting of ice = Rate of freezing of water. The system here is in dynamic equilibriums and following can be inferred.
- Equilibrium involving Dissolution of Solid in Liquid. Solution: When a limited amount of salt or sugar or any solute dissolves in a given amount of water solution is formed.
- Equilibrium between a Gas and its Solution in Liquid. This type of equilibrium can be seen by the following example: Let us consider a sealed soda water bottle in which C02 gas is dissolved under high pressure.
Equilibrium is attained when molecules leaving the liquid to vapour equals the molecules returning to the liquid from vapour. K c is the equilibrium constant. It is defined as the concentration of products divided by the concentration of reactants where each term is raised to the stoichiometric coefficient. Kc = [C] c [D] d / [A] a [B] b.
- It states that changes in the temperature, pressure, volume, or concentration of a system will result in predictable and opposing changes in the sy...

- Electrolytes are minerals in your blood and other body fluids that carry an electric charge.
Revision Notes Class 11 Chemistry Chapter 7 – Equilibrium. Introduction: biological process is meant to be chemical equilibrium. When a liquid evaporates in a closed container, molecules with relatively higher kinetic energy escape the liquid surface into the vapour phase and number of liquid molecules from the vapour phase strike .
Equilibrium Class 11 Notes – The chapter teaches that the number of molecules that leaves the liquid is equal to the number of molecules returning to the liquid from vapour. Moreover, equilibrium is dynamic in nature. Also, it can be established for both chemical and physical processes.
identify dynamic nature of equilibrium involved in physical and chemical processes; state the law of equilibrium; explain characteristics of equilibria involved in physical and chemical processes; write expressions for equilibrium constants; establish a relationship between. K and Kc;
