Helium atom is two times heavier than a hydrogen molecule. At 298 K, the average kinetic energy of the helium atom is

Question 1

(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.

Question 2

Correct option (b) same as that of a hydrogen molecule

Explanation:

Average kinetic energy per mole does not depend on the nature of the gas i. e., molecular mass of the gas depends only on temperatrue.

Average kinetic energy per molecule = 3/2 KT

k = Boltzmann constant, T = Temperature.
