Question
The average translational kinetic energy of O2 (molar mass 32) molecules at a particular temperature is 0.048 eV. The translational kinetic energy of N2 (molar mass 28) molecules in eV at the same temperature is
Options
A.0.0015
B.0.003
C.0.048
D.0.768
Solution
Average translational kinetic energy of an ideal gas molecules is 
kT which depends ontemperature only.
Therefore, if temperature is same, translational kinetic energy of O2 and N2 both will be equal.
kT which depends ontemperature only. Therefore, if temperature is same, translational kinetic energy of O2 and N2 both will be equal.
