Question

The graphs representing distribution of molecular speeds at $300 K$ for gases $Cl _{2}$ and $N _{2}$ are as shown in figure (atomic mass $N =14, Cl =35.5)$

• A. I graph is for $N _{2}$ and II is for $Cl _{2}$
• B. II graph is for $N _{2}$ and $I$ is for $Cl _{2}$
• C. either graph can be taken for $N _{2}$ or $Cl _{2}$
• D. information is not sufficient.

Answer 1

Answer: (B)

Molecular weight of $Cl^{2}$ is more than molecular weight of $N_ {2}$.
