| Which of the following pairs of gases would diffuse into the vacuum at the same speed? |
| [Given: Atomic mass of H=1u, C=12u, N=14u, S=32u, O=16u] |
A) \[\text{N}{{\text{H}}_{\text{3}}}\] and \[{{\text{H}}_{2}}\]
B) \[\text{CO}\] and\[\text{S}{{\text{O}}_{2}}\]
C) \[\text{CO}\] and\[{{\text{N}}_{2}}\]
D) \[\text{N}{{\text{H}}_{\text{3}}}\] and \[{{\text{N}}_{\text{2}}}\]
Correct Answer: C
Solution :
Rate of diffusion depends upon the molecular mass of gases. \[\text{CO}\] and \[{{\text{N}}_{2}}\] have the same molecular mass hence, both will diffuse at the same rate.
