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

`15 RT`

B

`9 RT`

C

`11 RT`

D

`4 RT`

Text Solution

Verified by Experts

`U = U_(O_(2)) + U_(Ar) = 2 xx (5)/(2) RT + 4 xx (3)/(2) RT = 11 RT`
