If in the reaction N_(2)O_(4)hArr2NO_(2),alpha is that part of N_(2)O_(4) which dissociates, then the number of moles at equilibrium will be

Answer»

3
1
`(1-alpha)^(2)`
`(1+alpha)`

Solution :`underset((1-alpha))underset(1)(N_(2)O_(4))hArrunderset(2alpha)underset(0)(2NO_(2))`
total mole at EQULIBRIUM `=(1-alpha)+2alpha=1+alpha`
