Maxwell's Speed of Distribution Law

Q. Select the incorrect statement about Maxwell’s distribution.

1. Most of the molecules move with speed $V_{mps}$
2. $V_{rms}>V_{av}>V_{mps}$
3. The area under distribution curve gives the total number of molecules of the gas
4. The distribution curve is symmetric about the most probable speed

Q. According to Maxwell's speed distribution law for a gas confined in a container, which of the following statements is/are correct:

1. All the molecules in the container will have certain non zero speed
2. Some of the molecules will have zero speed
3. There will be no molecules travelling with the same speed
4. Molecules travelling with very high speeds are lesser in number

Q. Identify the correct order as indicated in the given diagram of different kind of speed of molecules of same gas.


$f\left(v\right)\to$ Maxwell speed distribution function
$v_{mp}\to$ Most probable speed
$v_{rms}\to$ Root mean square speed
$v_{av}\to$ Average speed

1. $v_{mp}-3,v_{av}-2,v_{rms}-1$
2. $v_{mp}-1,v_{av}-2,v_{rms}-3$
3. $v_{mp}-2,v_{av}-1,v_{rms}-3$
4. $v_{mp}-3,v_{av}-1,v_{rms}-2$

Q.
