One mole of an ideal monoatomic gas is mixed with one mole of an equimolar mixture of monoatomic and diatomic ideal gases. Find the value of `lambda= (C_P /C_v)` for the final mixture

A

`8/7`

B

`19/12`

C

`11/7`

D

`8/5`

Text Solution

Verified by Experts

The correct Answer is:
C
`gamma=(15/2R+1(1/25/2R+1/2 7/2R))/(1 3/2R+1(1/2 3/2+R+1/2 5/2R)) =11/7`
