  3. No effect on the equilibrium position
  4. Increases the temperature

Questions & Step-by-Step Solutions

In a reaction at equilibrium, what is the effect of decreasing the volume of the container?
  • Step 1: Understand that a reaction at equilibrium means the forward and reverse reactions are happening at the same rate.
  • Step 2: Know that decreasing the volume of the container makes the space smaller for the gases inside.
  • Step 3: Realize that when the volume decreases, the pressure inside the container increases.
  • Step 4: Remember Le Chatelier's Principle, which states that if a change is made to a system at equilibrium, the system will adjust to counteract that change.
  • Step 5: Identify that increasing pressure will cause the equilibrium to shift towards the side of the reaction with fewer moles of gas.
  • Step 6: Conclude that by decreasing the volume, the equilibrium will shift to the side with fewer gas molecules to reduce the pressure.
