How does Le Chatelier's Principle allow you to predict the change of the position of equilibrium for an equilibrium reaction?
Le Chatelier's principle states that the position of equilibrium will shift to oppose the change of conditions to a system. For example, if the temperature is increased the position of equilibrium will shift towards the endothermic direction of reaction, or if the pressure is increased the position of equilibrium will move in the direction with the fewest gaseous moles of substance.
