Question: In the equilibrium reaction A(g) + B(g) ⇌ C(g), if the volume is increased, what will happen?

Options:

  1. Shifts to the right
  2. Shifts to the left
  3. No effect
  4. Increases the concentration of C

Correct Answer: Shifts to the right

Solution: 

Increasing the volume decreases the pressure, and according to Le Chatelier\'s Principle, the equilibrium will shift to the right to favor the formation of more gas molecules (C).

Questions & Step-by-Step Solutions

In the equilibrium reaction A(g) + B(g) ⇌ C(g), if the volume is increased, what will happen?
  • Step 1: Understand that A(g), B(g), and C(g) are gases in a reaction.
  • Step 2: Know that increasing the volume of the container means there is more space for the gases.
  • Step 3: Realize that when the volume increases, the pressure inside the container decreases.
  • Step 4: Remember Le Chatelier's Principle, which states that if a system at equilibrium is disturbed, it will shift to counteract the disturbance.
  • Step 5: Since the pressure decreases, the equilibrium will shift to the side with more gas molecules to increase the pressure.
  • Step 6: In this reaction, there are 2 gas molecules (A and B) on the left and 1 gas molecule (C) on the right.
  • Step 7: Therefore, the equilibrium will shift to the right to produce more C, which means more gas molecules overall.
  • Le Chatelier's Principle – This principle states that if an external change is applied to a system at equilibrium, the system will adjust to counteract that change and restore a new equilibrium.
  • Gas Laws – Understanding how changes in volume and pressure affect gaseous reactions and equilibria.
