Which statements correctly describes a system in chemical equilibrium?

There are statements that correctly describe a system in chemical equilibrium and help to determine the conditions of a chemical reaction in equilibrium.

Chemical equilibrium is said to be in dynamic meaning that the state is not permanent but can be altered with time when conditions like temperature, Pressure called external constraints changes.

First, we need to fully understand this concept, there is a need to reemphasize that chemical equilibrium is a state in chemical system when the rate of forward reaction equals the rate of backward reactions.

What can make a chemical reaction in dynamic equilibrium?

To full explain how to cerise a system in chemical equilibrium, I will briefly talk about the principle that govern dynamic equilibrium system.

Le Chatelier’s Principle states that if an external constraints such as change in Temperature, Concentration and Pressure is imposed on a system in equilibrium, the equilibrium position will shift in order to annul or counterbalance the effect.

So which statements correctly describes a system in chemical equilibrium?

A system in dynamic equilibrium is characterized by so many features

The word dynamic indicates we also have static equilibrium.

Dynamic equilibrium simply means that the equilibrium state is not permanent but temporal

Static equilibrium simply means that the equilibrium state is not temporal but permanent as a result external constraints do not affect it.

What is dynamic equilibrium in chemical reactions?

Dynamic equilibrium in reversible chemical systems is observed when there is no observable change in the state of the system with respect to time and this only occurs when the rate of forward reaction equals the rate of backwards reactions.

It is important to mention that in such state the concentrations of reactants and products remains constant.

When do dynamic equilibrium occur in reversible reactions?

A reversible reaction is said to be in dynamic equilibrium when the rate of forward reaction equals the rate of backward reaction in such a way that there is no net change in the concentrations of reactants and products with respect to time.

However it is also relevant to mention that dynamic equilibrium in chemical reactions is only attained and do not just exist in chemical reactions.

Moreover, according to Le Chateliers Principle. Chemical systems prefer to maintain dynamic equilibrium even when external constraints are imposed on the system, they do so by shifting the equilibrium position in order to annul or neutralize the changes caused by imposing the external constraints.

The constraints that are imposed necessitates the equilibrium position to shift to right or left while upsetting the changes in Temperature, Pressure, and Concentration. So the equilibrium position tends to maintain equilibrium position by fighting these changes and thus neutralizes it.

Which statements correctly describes a system in chemical equilibrium?

There are statements for a chemical system to be in dynamic chemical equilibrium and these feature heralds the properties of a chemical system in dynamic chemical equilibrium,.

Properties or statements of a system in dynamic equilibrium
1.The rate of forward reaction equals the rate of backward reaction
2. The concentrations of reactants and products remains constant
3.The chemical reaction or system must be reversible
4. The reaction must occur in a closed system,
5.The amount of reactants and products do not need to be equal

Le Chateliers Principle and chemical equilibrium

The Le Chateliers Principle states that if an external constraint such as change in Temperature, Pressure or concentration is imposed on system in dynamic equilibrium, the equilibrium position will shift in order tom annul or neutralize the constraint.

This means that when these changes re imposed, then equilibrium position either shift to the left or right in order to neutralize the effect.

In conclusion, the equilibrium position either shift or right in order to neutralize effects caused by these changes and it is important to remember that the properties of the system in dynamic equilibrium remains the same in such situation.
