Question: If a reaction is at equilibrium and the volume of the container is decreased, what will happen?

Options:

Correct Answer: Shift to the side with fewer moles of gas

Solution:

Decreasing the volume increases the pressure, which shifts the equilibrium towards the side with fewer moles of gas.

If a reaction is at equilibrium and the volume of the container is decreased, what will happen?

Step 1: Understand that a chemical reaction can reach a state called equilibrium, where the forward and reverse reactions occur at the same rate.
Step 2: Know that the reaction takes place in a container that has a certain volume.
Step 3: When the volume of the container is decreased, the space for the gas molecules becomes smaller.
Step 4: This decrease in volume causes the pressure inside the container to increase.
Step 5: According to Le Chatelier's principle, if the pressure increases, the equilibrium will shift to reduce that pressure.
Step 6: The equilibrium will shift towards the side of the reaction that has fewer moles of gas, as this will help decrease the pressure.

Le Chatelier's Principle – This principle states that if a system at equilibrium is subjected to a change in conditions (such as pressure, temperature, or concentration), the system will adjust to counteract that change and restore a new equilibrium.
Gas Laws – Understanding how changes in volume affect pressure and the behavior of gases is crucial in predicting the direction of the equilibrium shift.
