Vedclass · Answer

(D) The average speed $(v_{avg})$ of a gas molecule is given by the formula $v_{avg} = \sqrt{\frac{8RT}{\pi M}}$,where $R$ is the universal gas constant,$T$ is the temperature,and $M$ is the molar mass of the gas. Since the temperature $T$ is the same for both $SO_2$ and $O_2$,the average speed is inversely proportional to the square root of the molar mass $(v_{avg} \propto \frac{1}{\sqrt{M}})$. The molar mass of $SO_2$ is $64 \ g/mol$ and the molar mass of $O_2$ is $32 \ g/mol$. Since $M(SO_2) > M(O_2)$,the average speed of $SO_2$ will be smaller than that of $O_2$.

Consider a mixture of $SO_2$ and $O_2$ kept at room temperature. Compared to the oxygen molecule,the $SO_2$ molecule will hit the wall with
