If `alpha` is the degree of dissociation of `N_(2)O_(4)` in the reaction :
`N_(2)O_(4)hArr 2NO_(2)`
then at equilibrium, the total number of moles of `N_(2)O_(4)` and `NO_(2)` present is :

A

2

B

`1-alpha`

C

`(1-alpha)^(2)`

D

`1+alpha`

Text Solution

Verified by Experts

The correct Answer is:
D
`N_(2)O_(4)hArr 2NO_(2)`
If `alpha` is the degree of dissociation
`1-alpha " " 2alpha`
Total no. of moles `=1-alpha+2alpha=1+alpha`
