Dynamic Nature of Chemical Equilibrium
Understanding the characteristics of chemical equilibrium as a dynamic state where forward and reverse reaction rates are equal.
What is Dynamic Nature of Chemical Equilibrium?
A state in a reversible reaction where the rate of the forward reaction equals the rate of the reverse reaction, resulting in no net change in the concentrations of reactants and products.
Key points
- Define chemical equilibrium.
- Explain the dynamic nature of chemical equilibrium.
- Differentiate between static and dynamic equilibrium.
- Identify the conditions under which equilibrium is established.
Common exam trap
Confusing equilibrium with the completion of a reaction.
Definitions
- Term
Chemical Equilibrium
- Meaning
A state in a reversible reaction where the rate of the forward reaction equals the rate of the reverse reaction, resulting in no net change in the concentrations of reactants and products.
- Term
Dynamic Nature
- Meaning
The characteristic of chemical equilibrium where reactions continue to occur in both forward and reverse directions at equal rates, even though there is no observable change in the overall system.
- Term
Reversible Reaction
- Meaning
A reaction that can proceed in both the forward (reactants to products) and reverse (products to reactants) directions.
