For the specific heat of 1 mole of an ideal gas at constant pressure `(C_p)` and at constant volume `(C_v)` which is correct

A

`C_P` of hydrogen gas is `5/2` R

B

`C_V` of hydrogen gas is `7/2R`

C

`H_2` has very small values of `C_P and C_V`

D

`C_P-C_V=1.99` cal/mol-K for `H_2`

Text Solution

Verified by Experts

The correct Answer is:
D
`C_P-C_V=1.99 " cal"//mol -K` for `H_2`
Since, R=1.98 cal `mol^(-1)K^(-1)=8.31 " J mol"^(-1)K^(-1)`
