In the dissociation of `N_(2)O_(4)` into `NO_(2). (1+x)` values with the vapour densities ratio `((D)/(d))` is given by `:`

Options

A.
B.
C.
D.

Answer

A

Explanation

`N_(2)O_(4)(g)hArr 2NO_(2)(g)`
Here `y=2`
Degree of dissociation,
`x=(D-d)/(d(y-1))`
`x=(D-d)/(d)`
`x=(D)/(d)-1`
`1+x=(D)/(d)`
A graph between `1+x` ( along Y-axis) and `(D)/(d)` (along X-axis) , is a straight line passing through origin.
`(y-mx` type ) with slope, `m=1`.
