`N_(2)O_(4)(g)hArr2NO_(2)(g)` for the reaction if the percentage dissociation of `N_(2)O_(4)` are 25%, 50%, 75% and 100% then the sequence of observed vapour densities will be `(d_(1),d_(2),d_(3)` and `d_(4)` are vapour density at 25%, 50%, 75% and 100% dissociation respectively)

Options

A. `d_(1)gtd_(2)gtd_(3)gtd_(4)`
B. `d_(4)gtd_(3)gtd_(2)gtd_(1)`
C. `d_(1)=d_(2)=d_(3)=d_(4)`
D. `(d_(1)=d_(2))gt(d_(3)gtd_(4))`

Answer

A

Explanation

`alpha=(D-d)/((n-1)d)`
`alpha=(D-d)/d`
`d=D/(alpha+1)`
More `alpha` Less d
