The average translational kinetic energy...

The average translational kinetic energy of `O_(2)` (molar mass 32) molecules at a particular temperature is `0.048` eV. The translational kinetic energy of `N_(2)` (molar mass 28) molecules in eV at the same temperature is

A

`0.0015`

B

`0.003`

C

`0.048`

D

`0.768`

Text Solution

Verified by Experts

The correct Answer is:
C
Average translational kinetic energy of an ideal gas molecule is 3/2 KT which depends on temperature only. Therefore if the temperature is the same, translational kinetic energy of `O_2` and `N_2` both will be equal.
