Question: In the reaction 2SO2(g) + O2(g) ⇌ 2SO3(g), what will happen if the volume of the container is increased? (2023)

Options:

Shift to the right
Shift to the left
No change
Increase in temperature

Correct Answer: Shift to the left

Exam Year: 2023

Solution:

According to Le Chatelier\'s principle, increasing the volume of the container decreases the pressure. The equilibrium will shift towards the side with more moles of gas, which is the left side (2 moles of SO2 + 1 mole of O2).

In the reaction 2SO2(g) + O2(g) ⇌ 2SO3(g), what will happen if the volume of the container is increased? (2023)

Step 1: Identify the reaction: 2SO2(g) + O2(g) ⇌ 2SO3(g).
Step 2: Count the number of gas moles on each side of the reaction.
Step 3: On the left side, there are 2 moles of SO2 and 1 mole of O2, totaling 3 moles.
Step 4: On the right side, there are 2 moles of SO3, totaling 2 moles.
Step 5: Understand that increasing the volume of the container decreases the pressure inside.
Step 6: According to Le Chatelier's principle, the system will try to counteract the change (decrease in pressure) by shifting the equilibrium.
Step 7: The equilibrium will shift towards the side with more moles of gas, which is the left side (3 moles) in this case.

Le Chatelier's Principle – This principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.
Gas Moles and Volume Relationship – Understanding how changes in volume affect the pressure and the direction of the equilibrium shift based on the number of moles of gas.
