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 the equilibrium position when the concentration of a reactant is decreased?

Back

The equilibrium position shifts to the left to increase the concentration of the reactant.

Front

How does increasing pressure affect a reaction at equilibrium?

Back

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

Front

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

Back

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

Front

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

Back

Removing a product shifts the equilibrium position to the right to produce more of the product.

Front

Define dynamic equilibrium.

Back

Dynamic equilibrium is a state in which the rates of the forward and reverse reactions are equal, resulting in no net change in the concentrations of reactants and products.

Front

What is the significance of the equilibrium constant (K)?

Back

The equilibrium constant (K) quantifies the ratio of the concentrations of products to reactants at equilibrium at a given temperature.

Front

How does a catalyst affect the position of equilibrium?

Back

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

Front

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

Back

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

Front

What does it mean for a reaction to shift to the right?

Back

A shift to the right means that the formation of products is favored, increasing their concentration.
