Assertion : Mean free path of a gas mole...

Assertion : Mean free path of a gas molecule varies inversely as density of the gas.
Reason : Mean free path varies inversely as pressure of the gas.

A

If both assertion and reason are true and the reason is correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true, but the reason is false.

D

If assertion is false but the reason is true

Text Solution

Verified by Experts

The correct Answer is:
B
The mean free path of a gas molecule is the average distance between two successive collisions. It is represented by `lambda`
`lambda=(kT)/(sqrt(2)pisigma^(2)rho)`
Hence, mean free path varies inversely as density of the gas. It can be easily proved that the mean free path varies directly as the temperature and inversely as the pressure of the gas.
