The RMS speeds of the molecules of two gases A and B are in the ratio 0.866: 1 at 27°C for A and 127°C for B. Gases A and B may be
Options:(select one or more)
Answer:
A, B, C
Solution:
uA/uB = √(TA·MB / (TB·MA)) = √(300·MB / (400·MA)) = 0.866 = √(3)/2. Squaring: 3MB/(4MA) = 3/4, so MA = MB. Pairs with equal molar masses: N2 and CO (28), O2 and N2H4 (32), N2O and CO2 (44). SO2 (64) and SO3 (80) differ. Hence (a), (b), (c).
