Solution

The correct option is C Both have the same average kinetic energy per mol
Moles of $C H_{4} =$ 4 times of moles of $S O_{2}$ , So $p_{C H_{4}} = 4 p_{S O_{2}}$

$\frac{r_{C H_{4}}}{r_{S O_{2}}} = \frac{p_{C H_{4}}}{p_{S O_{2}}} \sqrt{\frac{M_{S O_{2}}}{M_{C H_{4}}}} = \frac{4}{1} \sqrt{\frac{64}{16}} = 8$

$\frac{{¯ V}_{C H_{4}}}{{¯ V}_{S O_{2}}} = \sqrt{\frac{M_{S O_{2}}}{M_{C H_{4}}}} = 2$
K.E. (per mol) $= (\frac{3}{2}) R T$ , So same for both.
Partial pressure of a gas is directly proportional to mole fraction of that particular gas.
