Question

The distribution of molecules with velocity is represented by the curve.

Velocity corresponding to point $A$ is :

• A. $\sqrt{\frac{3RT}{M}}$
• B. $\sqrt{\frac{2RT}{M}}$
• C. $\sqrt{\frac{8RT}{\pi M}}$
• D. $\sqrt{\frac{RT}{M}}$

Answer 1

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

Point $A$ represents the most probable distribution of molecules. Hence, the most probable velocity is
$\sqrt{\frac{2RT}{M}}$
