Assertion: The root mean square and most probable speeds of the molecules in a gas are the same.
Reason: The maxwell distribution for the speed of molecules in a gas is symmetrical.

A

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

B

if both assertion and reason are true but reason is not the correct expalanation of the assertion

C

if assertion is true , but reason is false

D

both assertion and reason are false statements.

Text Solution

Verified by Experts

The correct Answer is:
D
`V_(r.m.s)=sqrt((3kT)/(m)) or , sqrt((3RT)/(M))`
`V_("probable")=sqrt((2kT)/(m)) or , sqrt((3RT)/(M))`
`:.` Assertion is wrong.
