If ideal diatomic gas follows the proces...

If ideal diatomic gas follows the process, as shown in graph, where `T` is temperature in kelvin and `V` is volume `(m^(3))`, then molar heat capacity for this process will be [in terms of gas constant `R]`:

A

`(7R)/(2)`

B

`5R`

C

`(19R)/(6)`

D

`(11R)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`C = Cv +(R )/(1-eta) ……..(i)`
`T^(2) V^(-3) =` constant `, PV = nRT`
`P^(2)V^(2)V^(-3) =` constat `, P^(2)V^(-1) =` constant
`PV^(-1//2) =` constant
`N =- 1//2`
`C = (5R)/(2) +(2R)/(3) =(19R)/(6)`
