Checking Equilibrium With an Added Inert Gas
Base your answers on the information provided and your knowledge of chemistry. Use the 2025 Chemistry Reference Tables as needed.
A model gas reaction is A ⇌ 2 B. It is initially at equilibrium at fixed temperature. A chamber contains six A and six B particle units in volume three. In the model each gas’s pressure contribution equals its count divided by volume. A separate inert gas does not react.
Question 1
Which trial keeps both reactive pressure contributions at their original values just after the addition?
- P only
- Q only
- Both trials
- Neither trial
Question 2
Find the total pressure just after adding inert gas in each trial. Include the inert contribution.
Write your answer and work on the printable worksheet, or answer online.
In the display, adding inert gas at fixed volume leaves the original equilibrium unchanged. A volume increase favors the side with more gas particles until a new equilibrium is reached.
Question 3
Predict which trial changes its A-to-B composition as it settles and which side it favors.

Question 4
A student says the larger change in total pressure marks the trial with a composition shift. Evaluate the claim with the two trials.
