A gas mixture consists of 2 moles of oxygen and 4 moles of argon at temperature T. Neglecting all vibrational modes, the total internal energy of the system is

A

`15RT`

B

`9RT`

C

`11RT`

D

`4RT`

Text Solution

Verified by Experts

The correct Answer is:
C
`U=f/2 nRT`
`U_(t otal) = 5/2(2)RT+3/2(4)RT`
`U_(T otal) = 11RT`.
