A vessel contains a mixture of H2 and D2 gases. If a pin hole is made in the vessel, then
Options:(select one or more)
Answer:
B, C
Solution:
By Graham's law the lighter H2 (M = 2) effuses faster than D2 (M = 4), so the gas left behind gets richer in D2: the mole fraction of D2 increases and that of H2 decreases with time, and the average molecular weight of the remaining gas rises toward 4. The partial pressure of H2 falls both because its mole fraction falls and because the total pressure falls. Hence (b) and (c).
