Front

What is the definition of physical equilibrium?

Back

A state where the physical state of a system remains constant over time.

Front

What is the definition of chemical equilibrium?

Back

A state where the concentrations of reactants and products remain constant over time.

Front

Which of the following is NOT an example of chemical equilibrium?

Back

The dissolution of sugar in water.

Front

According to Le Chatelier's principle, what happens when the concentration of a reactant is increased?

Back

The equilibrium shifts to the right.

Front

What is Le Chatelier's principle?

Back

If a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change.

Front

What is dynamic equilibrium?

Back

A state of balance in a system where the rate of the forward reaction equals the rate of the reverse reaction.

Front

What is the effect of temperature on chemical equilibrium?

Back

Changing the temperature can shift the position of equilibrium; for exothermic reactions, increasing temperature shifts equilibrium to the left.

Front

What is a reversible reaction?

Back

A reaction that can proceed in both the forward and reverse directions.

Front

What is the equilibrium constant (K)?

Back

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