[본문내용]

(4페이지) Equilibrium state

At equilibrium:

The forward and reverse reactions are occurring at equal rates.

There is no change in the concentrations of reactants and products.

There is no change in macroscopic properties (ex. color and density).

The equilibrium can be approached from either forward or reverse direction.

The equilibrium is dynamic. The forward and reverse reactions continue but there is no overall change in concentrations of reactants and products.

Any changes in the reaction conditions (temp, pressure, concentrations) can affect the equilibrium.

(14페이지) Le Chatelier’s principle

Le Chatelier’s principle: If a change is made to a system that is in equilibrium, the balance between the forward and reverse reactions will shift to offset this change and return the system to equilibrium.

CHANGE IN CONCENTRATION

If the concentration of a reactant is increased, the forward reaction will be favored to counteract this change. Decreasing concentration of a product will also favor the forward reaction.
The reverse reaction will be favored if the concentration of a reactant is decreased or the concentration of a product is increased.

Kc remains unchanged as long as the temperature remains the same!
