Le Chatelier's Principle

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 and restore a new equilibrium.

How does increasing the concentration of a reactant affect the equilibrium position?

Back

Increasing the concentration of a reactant will shift the equilibrium position to the right, favoring the formation of products.

Front

What happens to the equilibrium position when the temperature is decreased in an exothermic reaction?

Back

Decreasing the temperature in an exothermic reaction shifts the equilibrium position to the right, favoring the formation of products.

Front

What effect does increasing pressure have on gaseous equilibria?

Back

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

Front

How does adding a catalyst affect the position of equilibrium?

Back

Adding a catalyst does not affect the position of equilibrium; it only speeds up the rate at which equilibrium is reached.

Front

What is the effect of decreasing the concentration of a product on the equilibrium position?

Back

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

Front

What is the relationship between the concentration of reactants and the rate of the forward reaction?

Back

An increase in the concentration of reactants increases the rate of the forward reaction.

Front

In a reaction at equilibrium, what does it mean if the concentrations of reactants and products remain constant?

Back

It means that the rates of the forward and reverse reactions are equal.

Front

What is the impact of a change in volume on gaseous equilibria?

Back

A decrease in volume increases pressure, which shifts the equilibrium towards the side with fewer moles of gas.

Front

What is the effect of temperature on an endothermic reaction at equilibrium?

Back

Increasing the temperature in an endothermic reaction shifts the equilibrium position to the right, favoring the formation of products.
