MCQ

Select the incorrect statement about Maxwell's speed distribution

A
The distribution function depends only on the absolute temperature
B
$V_{ ms } > V_{a v} > V_{m p}$
C
The area under the distribution curve gives total number of molecules of the gas
✓
The distribution curve is symmetric about the most probable speed

✓

Answer

Correct option: D.

The distribution curve is symmetric about the most probable speed

d
(d)

The Maxwell's speed distribution is asymmetric due to the fact that the lowest speed possible is zero. While the highest speed possible is infinity.
