List four characteristics of chemical Equilibrium?

1. Dynamic: Chemical equilibrium is a dynamic state where the rate of the forward reaction is equal to the rate of the reverse reaction.

2. Reversible: Chemical equilibrium is a reversible process, meaning that the reaction can proceed in both the forward and reverse directions.

3. Constant concentrations: In a state of equilibrium, the concentrations of reactants and products remain constant over time, although the reactions are still occurring.

4. Equilibrium constant: The equilibrium constant (Kc) is a numerical value that describes the ratio of product concentrations to reactant concentrations at equilibrium for a given reaction.

1. Reversible reaction: The forward and reverse reactions occur at the same rate, so there is no net change in the concentrations of the reactants and products.
2. Dynamic state: The concentrations of the reactants and products do not change over time, but there is constant motion of molecules between the two states.
3. Macroscopic unchanging composition: The overall composition of the system, as measured by the concentrations of the reactants and products, does not change over time.
4. Microscopic changing composition: At the molecular level, the system is constantly changing as molecules react and products are formed.
