Calculate the root mean square, average and most probable speed of oxygen at `27^(@)C`

Text Solution

Verified by Experts

`U_(rms)=sqrt((3RT)/(M))`
Take, R in J `mol^(-1) K^(-1)` and M in kg to have speed in `m//s`.
`U_(rms)=sqrt((2 xx 8.314 xx 300)/(32 xx 10^(-3)))=4.835 xx 10^(2) ms^(-1)`
`U_(rms)= 0.817 U_(rms)=0.817 xx 4.835 xx 10^(2) ms^(-1)= 3.950 xx 10^(2) ms^(-1)`
