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

Options

A. `0.0015`
B. `0.003`
C. `0.048`
D. `0.768`

Answer

C

Explanation

Average tranlational knetic energy of an ideal gas molecule is `3//2KT` which depends on temperature only. Therefore If the temperature is same, translational kinetic energy of `O_(2)` and `N_(2)` both will be equal.
