Equilibrium Graphs

Front

Define chemical equilibrium.

Back

The rate of a forward reaction is equal to the rate of the reverse reaction.

Front

What is the correct equilibrium constant expression for the reaction CaCO₃(s) ⇋ CaO(s) + CO₂(g)?

Back

K = [CO₂]

Front

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

Back

the same

Front

If a reaction is reversible and has reached equilibrium, what can be said about the amounts of reactants and products?

Back

some reactant, some product

Front

When the rate of the forward reaction is equal to the rate of backward reaction, the system is said to be in

Back

Chemical Equilibrium

Front

What does it mean for a reaction to be reversible?

Back

A reaction is reversible if it can proceed in both the forward and reverse directions.

Front

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

Back

The equilibrium constant (K) quantifies the ratio of the concentrations of products to reactants at equilibrium.

Front

What factors can affect the position of equilibrium?

Back

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

Front

What is Le Chatelier's Principle?

Back

Le Chatelier's Principle states that if a system at equilibrium is subjected to a change, the system will adjust to counteract that change.

Front

What happens to the equilibrium position if the concentration of reactants is increased?

Back

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