Which of the following represents total kinetic energy of one mole of gas?

A

`1//2RT`

B

`3//2RT`

C

`(C_(P) - C_(V))R`

D

`2//3RT`

Text Solution

Verified by Experts

The correct Answer is:
B
`PV = (1)/(3) mn v^(2) = (2)/(3) xx (1)/(2) m nv^(2) = (2)/(3) KE`
`PV = RT :. 2//3 KE = RT " or " 3//2 RT`
