Hydrogen molecues and oxygen molecules are at same temperature.
average kinetci energy is directly proportional to temperature. Hence their average kinetic energy will be same.
Oxygen molecules are heavier than hydrogen molecule. Sice their average kinetic energy is same,
average speed of oxygen molecule will be less in comparision with average speed of hydrogen
