Equilibrium and 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

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

Back

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

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings.

Front

How does increasing temperature affect an exothermic reaction at equilibrium?

Back

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

Front

How does decreasing the volume of a container affect gaseous equilibrium?

Back

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

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 effect of adding a catalyst to a reaction at 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 does it mean if the equilibrium constant (K) is greater than 1?

Back

If K > 1, it indicates that at equilibrium, the concentration of products is greater than that of reactants.

Front

What does it mean if the equilibrium constant (K) is less than 1?

Back

If K < 1, it indicates that at equilibrium, the concentration of reactants is greater than that of products.
