The rms speeds of the molecules of Hydrogen, Oxygen and Carbon dioxide at the same temperature are VH, VO and VC respectively then :
Solution
${V_{RMS}} = \sqrt {{{3RT} \over {{M_W}}}}$<br><br>At the same temperature ${V_{RMS}} \propto {1 \over {\sqrt {{M_W}} }}$<br><br>$\Rightarrow$ V<sub>H</sub> > V<sub>O</sub> > V<sub>C</sub><br><br>Option (a)
