Question 424: Thermodynamics & KTG

Question

A gas mixture consists of 3 moles of oxygen
and 5 moles of argon at temperature T.
Assuming the gases to be ideal and the oxygen
bond to be rigid, the total internal energy (in
units of RT) of the mixture is :

Accepted Answer

U $$ = {{{f_1}} \over 2}{n_1}RT + {{{f_2}} \over 2}{n_2}RT$$
$$ = {5 \over 2}\left( {3RT} ight) + {3 \over 2} 	imes 5RT$$
$$ 	herefore $$ U $$ = 15RT$$
