Relationship Between Kp Kc and Factors Affecting Equilibrium - Le Chatelier

In the equilibrium A(g) 2B(g) , what happens if B is removed at constant volume?

Removing B decreases its concentration, shifting the equilibrium right to produce more B , per Le Chatelier’s principle.

Relationship Between Kp Kc and Factors Affecting Equilibrium - Le Chatelier

In the equilibrium 2P(g) Q(g) + R(g) , adding Q at constant volume will shift the equilibrium in which direction?

According to Le Chatelier’s principle, adding Q increases its concentration, shifting the equilibrium left to reduce Q by forming more P .

Homogeneous and Heterogeneous Equilibria and Applications of Equilibrium Constant

What is the effect of adding an inert gas at constant volume to the equilibrium 2A(g) B(g) + C(g) ?

Adding an inert gas at constant volume does not change the partial pressures or concentrations of the reactants and products, so the equilibrium position remains unaffected.

Homogeneous and Heterogeneous Equilibria and Applications of Equilibrium Constant

In the equilibrium 2XY(g) X₂(g) + Y₂(g) , decreasing the volume shifts the equilibrium in which direction?

Increasing pressure (decreasing volume) favors the side with fewer moles of gas. Here, 2 mol → 2 mol , so Δ n = 0 , and there is no shift.

Chemical Equilibrium - Law of Mass Action and Equilibrium Constant

For 2X(g) Y(g) + Z(g) , if the volume is halved at constant temperature, the equilibrium shifts towards which direction?

Increasing pressure (halving volume) favors the side with fewer moles of gas. Here, 2 mol → 2 mol , Δ n = 0 , so there is no shift.

In the equilibrium A₂(g) 2A(g) , if Kp = 0.5 at 400 K, what happens when the volume is doubled at constant temperature?

Decreasing pressure (doubling volume) favors the side with more moles of gas. Here, Δ n = 2 - 1 = 1 , so the equilibrium shifts to the right (towards A ).
