The RMS speeds of the molecules of two gases A and B are in the ratio 0.707 : 1 at 27°C for A and 327°C for B. Gases A and B may be
Options:(select one or more)
Answer:
A, B, D
Solution:
uA/uB = sqrt(TA·MB/(TB·MA)) = sqrt(300·MB/(600·MA)) = 0.707 = 1/sqrt(2). Squaring: MB/(2MA) = 1/2, so MA = MB. Pairs with equal molar masses: CO and C₂H₄ (28), NO and C₂H₆ (30), N₂O and CO₂ (44). CH₄ (16) and O₂ (32) differ. Hence (a), (b), (d).
