Le Chatelier

Front

What is Le Chatelier's Principle?

Back

Le Chatelier's Principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.

Front

How does increasing temperature affect an exothermic reaction at equilibrium?

Back

Increasing temperature shifts the equilibrium position to the left, favoring the reactants.

Front

What happens to the equilibrium position when the concentration of a reactant is increased?

Back

The equilibrium position shifts to the right, favoring the formation of products.

Front

What effect does decreasing the volume of a gas reaction have on equilibrium?

Back

Decreasing the volume shifts the equilibrium position towards the side with fewer moles of gas.

Front

What is the effect of adding an inert gas to a reaction at equilibrium?

Back

Adding an inert gas at constant volume has no effect on the position of equilibrium.

Front

What is the relationship between pressure and equilibrium in gaseous reactions?

Back

Increasing pressure shifts the equilibrium position towards the side with fewer moles of gas.

Front

What is an example of a factor that does NOT affect the position of equilibrium?

Back

States of matter do not affect the position of equilibrium.

Front

What happens when a product is removed from a reaction at equilibrium?

Back

Removing a product shifts the equilibrium position to the right, favoring the formation of more products.

Front

How does the addition of a catalyst affect equilibrium?

Back

A catalyst speeds up the rate of reaching equilibrium but does not change the position of equilibrium.

Front

What is the effect of increasing the concentration of a product in a reaction at equilibrium?

Back

Increasing the concentration of a product shifts the equilibrium position to the left, favoring the formation of reactants.
