Helium atom is two times heavier than a hydrogen molecule, At 298 K, the average kinetic energy of the helium atom is
Options
(a) two times that of a hydrogen molecule
(b) same as that of a hydrogen molecule
(c) four times that of a hydrogen molecule
(d) half that of a hydrogen molecule
Correct Answer:
same as that of a hydrogen molecule
Explanation:
Average kinetic energy per mole does not depend on the nature of the gas, it depends only on temperature.
Average kinetic energy per molecule = 3/2 kT
k= Boltzman constant, T= temperature.
