Solution

The correct option is C 2 : 1
Kinetic energy for a single molecule is given as E=32kT
where k is Boltzman's constant so for 2n molecules of Hydrogen the kinetic energy will be EH2=2n(1.5kT)
And that for n molecules of O2 will be EO2=n(1.5kT)
ratio of energies will be EH2:EO2=2:1
Option C is correct.
