If in the reaction `N_(2)O_(4) = 2N_(2)` , `alpha` is that part of `N_(2)O_(4)` which dissociates, then the number of moles at equilibrium will be

A

3

B

1

C

`(1-alpha)^(2)`

D

`(1+alpha)`

Text Solution

Verified by Experts

The correct Answer is:
D
`underset((1-alpha))underset(1)(N_(2)O_(4))hArrunderset(2alpha)underset(0)(2NO_(2))`
total mole at equlibrium `=(1-alpha)+2alpha=1+alpha`
