At T(K), a hypothetical gas consisting of 100 molecules has the following distribution of velocities. (N = Number of molecules, V = velocity in cm `s^(-1)`).

The most probbable velocity (in cm `s^(-1)`) for this gas is

A

`4 times 10^(3)`

B

`4 times 10^(8)`

C

`6.8 times 10^(6)`

D

`2 times 10^(7)`

Text Solution

Verified by Experts

The correct Answer is:
C
Most probable velocity is the velocity attained by the maximum number of of molecules in gas.
Here, 35 is the maximum number of molecules, which has `6.8 times 10^(6)cm" "s^(-1)` velocity.
So, the most probable velcoity for this gas is
`" "=6.8 times 10^(6) cm " "s^(-1)`
