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.

Front

How does increasing the concentration of a reactant affect equilibrium?

Back

Increasing the concentration of a reactant shifts the equilibrium to the right, favoring the formation of products.

Front

What effect does adding a catalyst have on a chemical equilibrium?

Back

Adding a catalyst speeds up the rate of both the forward and reverse reactions equally, but does not change the position of equilibrium.

Front

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

Back

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

Front

What is the effect of decreasing the volume of a gas reaction at equilibrium?

Back

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

Front

How does increasing pressure affect a gaseous equilibrium?

Back

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

Front

What is the result of removing a product from a reaction at equilibrium?

Back

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

Front

What does it mean for a reaction to be at equilibrium?

Back

A reaction is at equilibrium when the rates of the forward and reverse reactions are equal, and the concentrations of reactants and products remain constant.

Front

How does temperature affect the position of equilibrium in an endothermic reaction?

Back

Increasing the temperature shifts the equilibrium to the right, favoring the formation of products.

Front

What is the role of a dynamic equilibrium in chemical reactions?

Back

Dynamic equilibrium allows for continuous reactions in both directions, maintaining constant concentrations of reactants and products.
