Given that, EO2=0.048 eV . We know that, E=(3/2)kT . Since, k is constant and according to the question, T is also constant. Thus, EN2=0.048 eV . As The average translational kinetic energy depends on temperature only.

Q. The average translational kinetic energy of $O_{2}$ (molar mass $32$ ) molecules at a particular temperature is $0.048 e V$ . The translational kinetic energy of $N_{2}$ (molar mass $28$ ) molecules in $e V$ ,at the same temperature is

$0.0015$

$0.036$

$0.048$

$0.768$

Given that,
$E_{O_{2}} = 0.048 e V$ .
We know that, $E = \frac{3}{2} k T$ .
Since, $k$ is constant and according to the question, $T$ is also constant.
Thus, $E_{N_{2}} = 0.048 e V$ .
As The average translational kinetic energy depends on temperature only.
