`gama` for `NH_(3)` including contribution from vibrataional degree's freedom is

A

`4//3`

B

`(10)/(9)`

C

`(7)/(6)`

D

`(13)/(12)`

Text Solution

Verified by Experts

The correct Answer is:
B
`C_(V)=(n_(tr))/(2)R+(n_(rot))/(2)R+n_(vib)R=(3)/(2)R+(3)/(2)R+6R=9R`
`C_(P)=9R+R=10R`
`gamma=(C_(P))/(C_(V))=(10)/(9)`
