Chemical Equilibrium Concepts

Front

What does Keq = 1 indicate about a chemical system?

Back

Equilibrium is established.

Front

What happens to the equilibrium constant (K) when the temperature increases for an exothermic reaction (-ΔH)?

Back

K decreases.

Front

What happens to the equilibrium constant (K) when the temperature decreases for an exothermic reaction (-ΔH)?

Back

K increases.

Front

What does Keq < 1 indicate about a chemical system?

Back

The system has mostly reactants and equilibrium lies to the left.

Front

What occurs when Q < K in a chemical reaction?

Back

Reactants are forming into products.

Front

Define chemical equilibrium.

Back

A state in a reversible reaction where the rates of the forward and reverse reactions are equal.

Front

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

Back

It quantifies the ratio of products to reactants at equilibrium.

Front

How does an increase in temperature affect K for an endothermic reaction (+ΔH)?

Back

K increases.

Front

What is the relationship between Q and K at equilibrium?

Back

Q = K.

Front

What does it mean if Q > K?

Back

The reaction will shift to the left, favoring reactants.
