Calculate the temperature at which rms velocity of `SO_2` is the same as that of oxygen at `27^@C`

Explanation

For `O_2,v_(rms)=sqrt((3RT)/M)=sqrt((3Rxx300)/32)`
For ` SO_2, v'_(rms)=sqrt((3RT')/M')=sqrt((3RT')/64)`
As v' = v
`:. sqrt((3RT')/64)=sqrt((3Rxx300)/(32))`
(or) `T'=600K = 600-273=327^@C`
