Vapour density of the equilibrium mixtur...

Vapour density of the equilibrium mixture of `NO_(2)` and `N_(2)O_(4)` is found to be 40 for the equilibrium `N_(2)O_(4) harr 2NO_(2)`. From this information answer the following
Degree of dissociation of `N_(2)O_(4)` is

A

0.18

B

0.15

C

0.12

D

0.1

Text Solution

Verified by Experts

The correct Answer is:
B
`(D)/(2)=1+(n-1)alpha=1+alpha`
`(46)/(40)=1+alpha, alpha=(6)/(40)=0.15`
