Equilibrium and equilibrium constant

Front

What does it mean if the equilibrium constant (K) is much less than one (K << 1)?

Back

Equilibrium lies to the left (reactants are favored).

Front

What is the Kc expression for the reaction: 2 NO(g) + O2(g) ⇌ 2 NO2(g)?

Back

Kc = [NO2]^2 / [NO]^2[O2].

Front

What is the concentration equilibrium constant expression for the reaction: N2O4(g) ↔ 2 NO2(g)?

Back

Kc = [NO2]^2 / [N2O4].

Front

What does the symbol '↔' indicate in a chemical reaction?

Back

It indicates that the reaction is reversible.

Front

At what time does a reaction reach equilibrium?

Back

At time t2.

Front

Define equilibrium in the context of chemical reactions.

Back

Equilibrium is the state in which the concentrations of reactants and products remain constant over time.

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

How does temperature affect the equilibrium constant (K)?

Back

The value of K changes with temperature; it is specific to a given temperature.

Front

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

Back

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

Front

What is Le Chatelier's Principle?

Back

Le Chatelier's Principle states that if a system at equilibrium is disturbed, the system will shift in a direction that counteracts the disturbance.
