Dimethyl ether decomposes as
CH3OCH3(g) → CH4(g) + CO(g) + H2(g)
when CH3OCH3 decomposes to 20% extent under certain conditions, what is the ratio of diffusion of pure CH3OCH3 with methane?
(a) 0.59 : 1
(b) 1.18 : 1
(c) 2.36 : 1
(d) 1.77 : 1

Correct answer: (c) 2.36 : 1
Explanation:
\(\frac{r_{CH_3OCH_3}}{r_{CH_4}}\)
= \(\sqrt{\frac{M_{CH_4}}{M_{CH_3OCH_3}}}\) x \(\frac{pCH_3OCH_3}{PCH_4}\)
= \(\sqrt{\frac{16}{46}}\) x \(\frac{0.8}{0.2}\) = 2.36:1
