Question

Which of the following statement(s) is/are correct? He escapes at a rate of:

• A. 8.65 times of $S{O}_3$
• B. 2.65 times of $CO$
• C. 11 times of $C{O}_2$
• D. 4 times of $S{O}_2$

Answer 1

Answer: (B), (D)

4 times of $S{O}_2$

$r\propto \frac{1}{\sqrt{M}}$
(a) $\therefore \frac{r_{He}}{r_{S{O}_3}}=\sqrt{\frac{80}{4}}=\sqrt{2}0=4.47$
(b) $\frac{r_{He}}{r_{CO}}=\sqrt{\frac{28}{4}}=2.65$

(c) $\frac{r_{He}}{r_{C{O}_2}}=\sqrt{\frac{44}{4}}=3.31$

(d) $\frac{r_{He}}{r_{S{O}_2}}=\sqrt{\frac{64}{4}}=4$
