What is meant by a dynamic equilibrium?
In chemistry, and in physics, a dynamic equilibrium exists once a reversible reaction occurs. Substances transition between the reactants and products at equal rates, meaning there is no net change. Reactants and products are formed at such a rate that the concentration of neither changes.
What do we mean by static equilibrium?
Static equilibrium refers to any system where the sum of the forces, and torque, on every particle of the system happens to be zero. Simply, it is the equilibrium of a system whose parts are at rest.
What is physical equilibrium?
Physical equilibrium is defined as the equilibrium which develops between different phases or physical properties. In these processes, there is no change in chemical composition. It represents the existence of the same substance in two different physical states.
What are the 2 types of equilibrium?
There are two kinds of mechanical equilibrium:
- static equilibrium and.
- dynamic equilibrium.
What do you mean by dynamic equilibrium explain with an example?
When a body remains in it’s state of uniform motion where two or more forces are acting on it, the body is said to be in dynamic equilibrium. Examples: 1) An aeroplane flying at a constant speed. 2) A train running with a constant speed.
What is static equilibrium and examples?
Static equilibrium occurs when there is no exchange between reactants and products. An example of static equilibrium is diamond turning into graphite. The difference is: in static equilibrium, the rates of the forward and reverse reactions are zero.
What is the purpose of static equilibrium?
Static equilibrium is a valuable analysis tool: for example, if two forces are acting on an object that is in static equilibrium, that means they add up to zero. If you know the direction and magnitude of one of the forces, you can write an equation to determine the magnitude and direction of the unknown force.
What is physical equilibrium example?
The equilibrium attained in physical processes is called physical equilibrium. Example: Ice(s) ⇌ Water(l) . It is a physical equilibrium because no chemical reaction is involved. At this temperature, the solid-state of a substance is in equilibrium with the liquid state of a substance.
What is difference between physical equilibrium and chemical equilibrium?
A physical equilibrium is an equilibrium state in which the physical state of the system does not change. Chemical equilibrium is the equilibrium state in which the concentrations of reactants and products is not changed with time.
What are types of equilibrium in physics?
There are three types of equilibrium: stable, unstable, and neutral.
