Question

The graphs representing distribution of molecular speeds at $300 \,K$ for gases $Cl_2$ and $N_2$ are as shown in figure :

Select the correct option.

• 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 $N_2$.
