At 333 K, which of the pairs of gases below would have the most nearly identical rates of effusion? A) N₂O and NO₂ B) CO and CO₂ C) NO₂and N₂O₄ D) N₂and O₂ E) CO and N₂

Question

Quizplus · Accepted Answer

The rates of effusion of gases are inversely proportional to the square root of their molar masses. CO and N2 have similar molar masses, leading to nearly identical rates of effusion.
