For an ideal diatomic gas, during any process `T = KV`, find out the molar heat capacity of the gas during process (neglecting vibrational degree of freedom)

Options

A. `(3R)/(2)`
B. `(5R)/(2)`
C. `(7R)/(2)`
D. `2R`

Answer

C

Explanation

`T=KV rArr PV^(0)=` constant
`C=(R )/(gamma-1)-(R )/(n-1)=(R )/((7)/(5)-1)-(R )/(0-1)=(5R)/(2)+R`
`(7R)/(2)`
