If in the reaction `N_2O_4 hArr 2NO_(2),alpha` is that part of `N_2O_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_2O_4)hArrunderset(2alpha)underset(0)(2NO_2)`
total mole at equilibrium `=(1-alpha) +2alpha =1 +alpha`
