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 (JEE 1997)
(a) 0.0015 (b) 0.003 ( c) 0.048 (d) 0.768

A

0.0015

B

0.003

C

0.048

D

0.768

Text Solution

Verified by Experts

The correct Answer is:
C
Average translation kinetic energy per molecule is 3/2 kT which depends only on temperature and not on molecular mass.
