Dimethyl ether decomposes as CH(3)OCH(...

Dimethyl ether decomposes as
`CH_(3)OCH_(3)(g)rarrCH_(4)(g)+CO(g)+H_(2)(g)`
When `CH_(3)OCH_(3)(g)` decomposes to 20% extent under certain conditions, what is the ratio of diffusion of pure `CH_(3)OCH_(3)(g)` with methane?

A

`0.59:1`

B

`1.18:1`

C

`2.36:1`

D

`1.77:1`

Text Solution

Verified by Experts

The correct Answer is:
c
(c) `(r_(CH_(3)OCH_(3)))/(r_(CH_(4)))=sqrt((M_(CH_(4)))/(M_(CH_(3)OCH_(3))))xx(P_(CH_(3)OCH_(3)))/(P_(CH_(4)))`
`=sqrt((16)/(46))xx(0.8)/(0.2)=2.36:1`
