Chemical Equilibrium

Front

What is Chemical Equilibrium?

Back

A state in a chemical reaction where the rate of the forward reaction equals the rate of the backward reaction, resulting in no net change in the concentration of reactants and products.

Front

What is a Product in a chemical reaction?

Back

A substance that forms as a result of a chemical reaction.

Front

What is a Reactant in a chemical reaction?

Back

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

Front

What does it mean when a system is at equilibrium?

Back

It means that the concentrations of reactants and products remain constant over time.

Front

How long does it typically take to reach equilibrium in a reaction?

Back

It varies depending on the reaction, but in the provided examples, it was 5 seconds and 70 minutes.

Front

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

Back

It quantifies the ratio of the concentrations of products to reactants at equilibrium at a given temperature.

Front

What factors can affect chemical equilibrium?

Back

Concentration, temperature, and pressure can all affect the position of equilibrium.

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 happens to the rate of reaction as equilibrium is approached?

Back

The rate of the forward reaction decreases while the rate of the backward reaction increases until they are equal.

Front

What is dynamic equilibrium?

Back

A state of balance in a system where the forward and reverse reactions occur at the same rate.
