Calculate gamma (ratio of C(p) and C(v))...

Calculate `gamma` (ratio of `C_(p)` and `C_(v)`) for triatomic linear gas at high temperature. Assume that the contribution of vibrational degree of freedom is 75% :

A

1.222

B

1.121

C

1.18

D

1.33

Text Solution

Verified by Experts

The correct Answer is:
c
(c) `C_(v)=(3)/(2)R+R+4Rxx(3)/(4)=(11)/(2)R,`
`C_(p)=(11)/(2)R+R=(13)/(2)R`
`(C_(p))/(C_(v))=(13)/(11)=1.18`
