The shift of equilibrium

Le Chatelier's Principle: If in an equilibrium system that interferes with the action given equilibrium system, then the reaction will occur that will minimize the action.

Factors that influence the equilibrium

1. concentration

- If the concentration is enlarged, the equilibrium will shift in the opposite direction

- If the concentration is reduced, the equilibrium will shift towards these substances

2. Volume or pressure

- If V> / P <, the equilibrium shifts to a larger number of coefficients

- If V , the equilibrium shifts to a smaller number of coefficients

3. temperature

- T >, then the equilibrium shifts endothermic

- T <, then the exothermic shift kesetimbagan

4. catalytic

- The catalyst does not affect the reaction

- Catalysts only accelerate the achievement of equilibrium

Note:

- If the number of moles to the left equal to right, then the change of pressure and volume do not affect the equilibrium

- For the equilibrium of heterogeneous systems, the coefficient (mol) are taken into account is the gas phase only.
