Answer: Hydrogen molecules will have greatest average speed.
Explanation:
The formula for average speed is :
[tex]\mu_{av}={\sqrt{\frac{8RT}{\pi\times M}}}[/tex]
R = gas constant
T = temperature
M = Molecular Mass
Now putting all the values:
[tex]\frac{\nu_{H_2}}{\nu_{O_2}}=\sqrt{\frac{8RT}{\pi\times M_{H_2}}}/{\sqrt{\frac{8RT}{\pi\times M_{O_2}}}[/tex]
[tex]\frac{\nu_{H_2}}{\nu_{O_2}}=\sqrt{\frac{16}{2}}[/tex]
[tex]\frac{\nu_{av}_{H_2}}{\nu_{av}_{O_2}}=8[/tex]
Thus average speed of hydrogen is 8 times the average speed of oxygen. Thus hydrogen molecules will have greatest average speed
