What is meant by dynamic equilibrium?

A reversible process is said to be in dynamic equilibrium when the forward and reverse processes occur at the same rate, resulting in no observable change in the system. Once dynamic equilibrium is established, the concentrations or partial pressures of all species involved in the process remain constant.


Why is it called a dynamic equilibrium?

Dynamic equilibrium only occurs in reversible reactions, and it's when the rate of the forward reaction is equal to the rate of the reverse reaction. These equations are dynamic because the forward and reverse reactions are still occurring, but the two rates are equal and unchanging, so they're also at equilibrium.

What is dynamic equilibrium equation?

Thus, the dynamic equilibrium equation of a body in a deformed configuration γ can be written in a standard form as(2.1)σij,j+ρbi−ρu¨i=0where ui, is the current (deformed) displacement, bi is the body force accelaration, ρ is the current density of powder and σij is the total (Cauchy) stress.


What is dynamic equilibrium in physics example?

For example, when you observe a car in motion, you will notice that it moves with a constant velocity on a straight road. This means that the car has no net external force acting on it. In other words, this equilibrium is classified as dynamic equilibrium.

What are the features of dynamic equilibrium Class 11?

The characteristics of a dynamic equilibrium are : The observable properties, such as concentration, density, colour, pressure, etc., remain constant at a constant temperature. Equilibrium can be attained from either direction. Usage of a catalyst does not alter the position of equilibrium.

What is dynamic equilibrium class 11th?

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.

What is dynamic equilibrium Toppr?

Though the chemical reaction obtained equilibrium, there is conversion of reactants to products and products to reactants in same amount. The reaction doesn't stop. But there is no change in concentrations of reactants and products. So the equilibrium is also called dynamic equilibrium.

What is static and dynamic equilibrium?

Static equilibrium is a state where bodies are at rest; dynamic equilibrium is a state where bodies are moving at a constant velocity (rectilinear motion). In both cases the sum of the forces acting on them is zero.


What is the difference between static and dynamic equilibrium in physics?

Answer: The major difference between static and dynamic equilibrium is that in a static equilibrium the body is motionless, while in dynamic equilibrium, the body moves at a constant velocity.

What are the 3 types of equilibrium?

Types of equilibrium:
  • Stable equilibrium.
  • Unstable equilibrium.
  • Neutral equilibrium.


What solution is dynamic equilibrium?

A dynamic equilibrium is established in a solution when particles return to the surface of the solid at the same rate as they are leaving. When you put salt in water, particles leave its surface, and it goes into solution (dissolves).


Why is it called dynamic?

Why is it called dynamic? Dynamic equilibrium in a chemical reaction is the condition in which the rate of the forward reaction equals the rate of the reverse reaction. Dynamic equilibrium is called dynamic because the forward and reverse reactions are still occurring; however, they are occurring at the same rate.

Why is dynamic equilibrium important?

In medicinal/ pharmaceutical chemistry, a drug having dynamic equilibrium states plays an important role in the delivery of the drug on the active site across the cell membrane in a dynamic fashion and also acts as self-protection for the active drug molecule.

What is meant by static equilibrium?

Static equilibrium refers to the physical state of the system, in which the components of the system are at rest and the net force acting on a system should be zero.


What are the two types of dynamic equilibrium?

To summarize, a dynamic equilibrium is characterized by two main properties:
  • The rate of the forward reaction and the rate of the backward reaction are equal.
  • The concentrations of reactants and products do not change.


Who discovered dynamic equilibrium?

Cato.

Between 1864 and 1879 Cato and Waage came up with the law of mass action. This law would allow for chemist to predict the behaviours of solutions in dynamic equilibrium. This theory has two aspects to it, one is the equilibrium and the second aspect would be refered to as the kinetic aspect.

What's the difference between steady state and dynamic equilibrium?

The main difference between equilibrium and steady state is that equilibrium is a state in which the rate of the forward reaction equals the rate of the backward reaction whereas steady state is the stage of a chemical reaction that has a constant concentration of an intermediate.


What is difference static and dynamic?

In general, dynamic means "energetic or forceful," while static means "stationary." In computer terminology, however, dynamic usually means "capable of action or change," while static means "fixed."

How is equilibrium and dynamic equilibrium different?

An equilibrium is a state of a system which shows no net change. Chemical equilibrium obtains this state when the reaction stops while the dynamic equilibrium obtains this state when the forward and backward reaction rates are equal.

Why is it called static equilibrium?

If an object is at rest and is in a state of equilibrium, then we would say that the object is at "static equilibrium." "Static" means stationary or at rest.


What is the difference between equilibrium and static equilibrium?

Static equilibrium is a form of equilibrium that occurs when an object is at rest. "Static" refers to the object being motionless while "equilibrium" refers to the object either having no net forces acting upon it or having all of its net forces balanced.

Why is equilibrium dynamic in nature Class 11?

Chemical equilibrium is dynamic in nature because, reactants change into products and products change into reactants even after equilibrium is achieved. But rate of forward and backward reactions are same.

What is static equilibrium class 11?

What is static equilibrium? This is the type of equilibrium in which the resultant of all the forces acting on the body is zero, i.e. the net acceleration of the body is zero, and the velocity of the body is also zero. It means that the body is at rest.


What is chemical equilibrium class 11?

Chemical equilibrium refers to the state of a system in which the concentration of the reactant and the concentration of the products do not change with time and the system does not display any further change in properties.

What is equilibrium in physics class 11?

Equilibrium of a Particle: When the net external force acting on a particle is zero, the particle is said to be in equilibrium. Applying the Newton's First Law of Motion to this situation, we can say that the particle is either at rest or in uniform motion.
