Q. The average translational kinetic energy of $O_2$ molecules (relative molar mass 32) at a particular temperature is 0.048 eV. The translational kinetic energy of $N_2$ molecules (relative molar mass 28) in $eV$ at the same temperature is

Solution:

Average translational K.E. of a molecule $ = \frac{3}{2} kT$ . It depends on temperature and not on molecular mass. Hence average translational K.E. for N$_2$ will also be 0.048 eV.
