Equilibrium and Le Chatelier's Principle (intro level - no Keq)

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 when you add a reactant to a system at equilibrium?

Back

Adding a reactant will shift the equilibrium to the right, favoring the formation of products.

Front

What is the effect of removing a reactant from a system at equilibrium?

Back

Removing a reactant will shift the equilibrium to the left, favoring the formation of reactants.

Front

How does increasing pressure affect a gaseous equilibrium?

Back

Increasing pressure will shift the equilibrium 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 will shift the equilibrium to the left, favoring the reactants.

Front

What does it mean for a reaction to reach equilibrium?

Back

A reaction reaches equilibrium when the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst speeds up the rate of a reaction without being consumed, but it does not affect the position of equilibrium.

Front

What happens to equilibrium when a product is removed?

Back

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

Front

What is dynamic equilibrium?

Back

Dynamic equilibrium is a state in which the forward and reverse reactions occur at the same rate, leading to no net change in the concentrations of reactants and products.

Front

How does the addition of inert gas affect equilibrium?

Back

Adding an inert gas at constant volume does not affect the position of equilibrium, as it does not change the partial pressures of the reactants or products.
