For following decomposition:
`N_(2)O_(4)(g)rarr2NO_(2)(g)`
Calculate vapour density of mixture at a time when `20%` of `N_(2)O_(4)` has been dissociated.
(Assume initially only `N_(2)O_(4)` were present)

A

110

B

92

C

76.67

D

38.33

Text Solution

Verified by Experts

`N_(2)O_(4)(g)rarr2NO_(2)(g)`
`a_(0)-a_(0)alpha 2a_(0)alpha`
`n_(avg)=(a_(0)xx92)/(a_(0)(1+alpha))=(92)/(1.2)=76.67`
V.D. `=(M_("av"))/(2)=(76.67)/(2)=38.33`
