Reversible reactions and dynamic equilibrium

What is a reversible reaction?

In a reversible reaction, the products can convert back to the reactants.

How do you indicate a reaction as reversible?

Reversible reactions are illustrated by the ⇋ sign.

What is the forward reaction?

When reactants convert to products.

What is the backwards reaction?

When products convert back to reactants.

What is a closed system?

A system where no atoms can enter or leave in order to influence the reactions.

A sealed container is an example of a closed system.

How do you indicate when a reaction has reached equilibrium?

The concentration of reactants and products remains constant.

What is dynamic equilibrium?

A reversible reaction reaches dynamic equilibrium when the rate of the forward reaction equals the rate of the backwards reaction.

There is no overall change in concentration of the reactants and products.
