The vapour density of `N_(2)O_(4)` at a certain temperature is `30`. Calculate the percentage dissociation of `N_(2)O_(4)` this temperature.

A

`53.3%`

B

`106.6%`

C

`26.7%`

D

None

Text Solution

Verified by Experts

The correct Answer is:
A
Mol. Wt. of `N_(2)O_(4)=92`
Vapour density, `D=(92)/(2)=46`
`N_(2)O_(4)(g) hArr 2NO_(2)(g)`
Here `y=2`
`d=30`
`x=(D-d)/(d(y-1))=0.533=53.3%`
