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

Text Solution

Verified by Experts

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