The vapour density of N(2)O(4) at a cert...

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.

Text Solution

Verified by Experts

`N_(2)O_(4)(g) hArr 2NO_(2)(g)`
Vapour density = 46
Applying the relationship `((d)/(D)=(1)/(1+x))` where d: vapour density of mixture and D: vapour density of `N_(2)O_(4)`.
`x=(D-d)/(d)=((46-30))/(30)=0.533` Degree of dissociation `=53.33%`
