Step 3: Recognize that decreasing the volume of the container increases the pressure inside.
Step 4: Recall Le Chatelier's principle, which states that if a system at equilibrium is disturbed, it will shift to counteract the disturbance.
Step 5: Determine the number of moles of gas on each side of the reaction: left side (A + B) has 2 moles, right side (C + D) has 2 moles.
Step 6: Since both sides have the same number of moles of gas, the equilibrium will not shift in either direction.
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.
Effect of Volume on Gas Equilibrium – Decreasing the volume of a gas reaction increases pressure, which can shift the equilibrium position depending on the number of moles of gas on each side of the reaction.
