question 16

Multiple Choice

What happens to the equilibrium between NO₂(g) and N₂O₄(g) in inert argon when the volume is increased and additional argon is added to maintain a constant total pressure?

• A) The ratio of NO₂ to N₂O₄ increases solely because of the increase in volume.
• B) The ratio of NO₂ to N₂O₄ increases solely because of the addition of argon.
• C) The ratio of NO₂ to N₂O₄ decreases solely because of the increase in volume.
• D) The ratio of NO₂ to N₂O₄ decreases solely because of the addition of argon.
• E) The ratio of NO₂ to N₂O₄ remains the same, as the effects of the two processes cancel.
