Assertion : The number of degrees of freedom of triatomic molecules is `6`
Reason : Triatomic molecules have three translational degrees of freedom and three rotational degrees of freedom.

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:
A
We know that for a diatomic gas `C_(v)=3R, C_(P)=4R`
`:. Gamma = (C_P)/(C_v) = 4/3`
But `gamma=1+2/f`
so , `1+2/f=4/3implies 2/f = 4/3-1=1/3`
`f=6`
Tus, option (a) is correct.
