Question

The temperature at which the most probably speed of oxygen is equal to the rms velocity of hydrogen at NTP is?

Answer 1

7200K

$v \: rms= \sqrt{ \frac{3rt}{m} }$

$v \: probable= \sqrt{ \frac{2rt}{m} }$

temperature at ntp is 300 Kelvin
molecular mass of oxygen is 32 units and that of hydrogen is 2 units
