Chemical Equilibrium

Front

What is chemical equilibrium?

Back

A state in a chemical reaction where the rates of the forward and reverse reactions are equal, resulting in no net change in the concentration of reactants and products.

Front

During equilibrium, the rates of the forward and reverse reaction are ________

Back

equal

Front

At what time is equilibrium established in a reaction?

Back

The time at which the concentrations of reactants and products remain constant.

Front

What is a forward reaction?

Back

The reaction that forms products from reactants.

Front

What does dynamic equilibrium mean?

Back

A condition of continuous, random movement of particles but no overall change in concentration of materials.

Front

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

Back

It quantifies the ratio of the concentrations of products to reactants at equilibrium for a reversible reaction.

Front

What factors can affect chemical equilibrium?

Back

Concentration, temperature, and pressure.

Front

What happens to equilibrium when the concentration of reactants is increased?

Back

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

Front

What is Le Chatelier's Principle?

Back

If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.

Front

What is the difference between a closed and an open system in terms of equilibrium?

Back

A closed system allows no exchange of matter with the surroundings, while an open system can exchange matter, affecting equilibrium.
