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 decreasing temperature affect an exothermic reaction?

Back

Decreasing the temperature favors the exothermic reaction, shifting the equilibrium to the right to produce more heat.

Front

What effect does increasing pressure have on gaseous reactions?

Back

Increasing pressure favors the side of the reaction with fewer moles of gas, shifting the equilibrium to that side.

Front

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

Back

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

Front

How does the addition of a catalyst affect equilibrium?

Back

A catalyst increases the rate of both the forward and reverse reactions equally but does not shift the position of equilibrium.

Front

What is the effect 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 is the relationship between temperature and equilibrium in an endothermic reaction?

Back

Increasing the temperature favors the endothermic reaction, shifting the equilibrium to the right to absorb the added heat.

Front

How does increasing the concentration of a product affect equilibrium?

Back

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

Front

What is the impact of decreasing pressure on a reaction with more moles of gas on the reactant side?

Back

Decreasing pressure favors the side with more moles of gas, shifting the equilibrium to the left.

Front

What is dynamic equilibrium?

Back

Dynamic equilibrium is a state in which the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.
