Here's a breakdown:
* Reversible Reaction: A chemical reaction where the reactants form products, and the products can also react to form the reactants. This is represented by a double arrow (⇌) in the chemical equation.
Example:
The reaction of nitrogen gas (N₂) and hydrogen gas (H₂) to form ammonia (NH₃) is reversible:
N₂(g) + 3H₂(g) ⇌ 2NH₃(g)
* Forward Reaction: The reaction where reactants form products.
* Reverse Reaction: The reaction where products react to form reactants.
Key Concepts:
* Equilibrium: In a reversible reaction, a state of dynamic equilibrium is reached where the rates of the forward and reverse reactions are equal. This means that the concentrations of reactants and products remain constant over time.
* Le Chatelier's Principle: This principle states that if a change of condition (temperature, pressure, concentration) is applied to a system in equilibrium, the system will shift in a direction that relieves the stress.
* Equilibrium Constant (K): This value indicates the relative amounts of reactants and products at equilibrium.
