Question

Distribution of fraction of molecules with velocity is represented in the figure.

Velocity corresponding to point $X$ is:

• A. $\frac{\sqrt{2}RT}{M}$
• B. $\frac{\sqrt{3}RT}{M}$
• C. $\frac{\sqrt{8}RT}{M}$
• D. None

Answer 1

The correct option is A $\frac{\sqrt{2}RT}{M}$

Velocity corresponding to the maxima of curve is most probable velocity given by $u_{mp}=\sqrt{\frac{2RT}{M}}$.
