Increasing order of rms velocities of H₂,O₂,N₂ and HBr is
Options
(a) H₂,O₂,N₂,HBr
(b) HBr,O₂,N₂,H₂
(c) H₂,N₂,O₂, HBr
(d) HBr,N₂,O₂,H₂
Correct Answer:
HBr,O₂,N₂,H₂
Explanation:
Increasing order of rms velocities of H₂, O₂, N₂ and HBr is HBr,O₂,N₂,H₂
rms velocity is inversely proportional to square root of molar mass M,
ν(rms) = √(3RT / M)
.·. rms velocity decreases with increase in molar mass.
