Question

what is meant by dynamic equilibrium? Explain with example​

Answer 1

Answer:

1. Dynamic equilibrium is when dissolution and crystallization happens at the same rate.
2. Which means at this case, the amount of solute getting dissolved in the solvent is equal to the amount of solute getting separated out of the solvent.

Answer 2

Answer:

Dynamic Equilibrium can be defined as the state of a given system in which the reversible reaction taking place in it stops changing the ratio of reactants and products, but there is a movement of substances between the reactants and the products.

This movement occurs at an equal rate and there is no net change of the reactant and product ratio.

A few important examples of dynamic equilibrium in our everyday life are listed below.

1. A new bottle of an aerated drink has a specific value for the concentration of the carbon dioxide present in the liquid phase in it. When the bottle is opened and half of the drink is poured out of it, the liquid carbon dioxide is slowly converted into gaseous carbon dioxide until a new point of equilibrium is reached, and the rate of conversion of CO2 from gas to liquid is equal to the rate of conversion of CO2 from liquid to the gaseous phase.
2. The single-phase system in which acetic acid undergoes dissociation, leading to an acid-base equilibrium. This state of dynamic equilibrium can be described by the following reaction. CH3COOH ⇌ CH3COO– + H+
3. In the gaseous phase, it can be observed in the dimerization of nitrogen dioxide. Reaction: 2NO2 ⇌ N2O4
4. Henry’s Law is applicable in the first example of dynamic equilibrium provided above, wherein the equilibrium concentration of carbon dioxide in the liquid phase is proportional to the partial pressure of the CO2 gas in the bottle.
5. Industrial synthesis of ammonia via Haber’s process. Reaction: N2 (g) + 3H2 (g) ⇌ 2NH3 (g).
