Le Châtelier's Principle

Front

What is Le Châtelier's Principle?

Back

Le Châtelier's Principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.

How does increasing pressure affect a gaseous equilibrium?

Back

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

Front

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

Back

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

Front

What is the effect of increasing the volume of a container on a gaseous equilibrium?

Back

Increasing the volume shifts the equilibrium towards the side with more moles of gas.

Front

In which state of matter do changes in pressure affect equilibrium?

Back

Changes in pressure only affect substances that are in the gaseous state.

Front

What is the equilibrium constant (K) and what does it represent?

Back

The equilibrium constant (K) is a numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium.

Front

What does it mean if K is much greater than 1?

Back

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

Front

What does it mean if K is much less than 1?

Back

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

Front

What is dynamic equilibrium?

Back

Dynamic equilibrium is a state in which the rate of the forward reaction equals the rate of the reverse reaction, resulting in no net change in the concentrations of reactants and products.

Front

How does temperature affect equilibrium?

Back

Changing the temperature can shift the position of equilibrium; for exothermic reactions, increasing temperature shifts left, while for endothermic reactions, it shifts right.
