Assertion : The rms velocity and most probable speeds of the molecules in a gas are same.
The Maxwell distribution curve for the speed of the molecules in a gas is symmetrical.

Options

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.

Answer

D

Explanation

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