Calculate the temperature at which the oxygen molecules will have the same rms velocity as the hydrogen molecules at `150^@C.` Molecular weight of oxygen is 32 and that of hydrogen is 2.

Text Solution

Verified by Experts

`v_(rms)=sqrt((3RT)/(M))" As "v_(1 rms)=v_(2 rms)`, therefore `T alpha M`
`T_(1)/T_2=(M_(1))/M_2, T_(2)=T_(1) (M_2/M_1), T_2=423 [(32)/2]`
`T_2=6768k, t_2=6768-273=6495^@C`
