Question

The ratio of most probable velocity to that of average velocity is.

A

$\pi / 2$

B

$2 / \pi$

C

$\sqrt { \pi } / 2$

D

$2 / \sqrt { \pi }$

Answer

$\sqrt { \pi } / 2$

Explanation

Solution

$\frac { V _ { m p } } { V _ { a v } } = \frac { \sqrt { \frac { 2 R T } { M } } } { \sqrt { \frac { 8 R T } { \pi M } } } = \frac { \sqrt { \pi } } { 2 }$
