The behaviour of gases has been experessed in terms of various gas laws obtained experimentally Boyle s law Charles law Pressure temperature law Dalton s law of partial pressure Graham's law of diffusion and Avogadro's hypothesis Later on Maxwell derived Kinetic equation `PV = (1)/(3) mnu^(2)` theoretically by assuming the concept of molecules and their motion The term u reprsents root mean square speed of molecule
The `u_(rms)` of `SO_(2)` at `27^(@)C` is .

Options

A. `3.42 xx 10^(2) m sce^(-1)`
B. `10.82 m sec^(-1)`
C. `11.69 xx 10^(4) msec^(-1)`
D. none of these

Explanation

`u_(rms) =sqrt((3RT)/(M))= sqrt((3xx8.314 xx 300)/(64 xx 10^(-3)))`
` =3.42 xx 10^(2) m sec^(-1)` .
