Chemical Equilibrium

Front

What is a reactant?

Back

A substance that takes part in and undergoes change in a chemical reaction.

Front

What is a product?

Back

A substance that forms in a chemical reaction.

Front

During equilibrium, the amount of the products and the amount of the reactants are __________.

Back

Constant (unchanging).

Front

At what time (in seconds) is equilibrium established?

Back

5 seconds.

Front

What is a forward reaction?

Back

The reaction that forms products from reactants.

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

What does it mean when a reaction is at equilibrium?

Back

The concentrations of reactants and products remain constant over time.

Front

What is the equilibrium constant (K)?

Back

A numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium.

Front

What factors can affect chemical equilibrium?

Back

Concentration, temperature, and pressure.

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.
