If, in the reaction N_(2)O_(4) harr 2NO_(2) x is that part of N_(2) O_(4) which dissociates, then the number of molecules at equilibrium will be

Answer»

1
3
`(1 + X)`
`(1 + x)^(2)`

Solution :No. of moles before dissociation No.
of moles after dissociation
`UNDERSET(1-x)underset(1)(N_(2)O_(4)) harr underset(2x)underset(0)(2NO_(2))`
Total number of moles at equilibrium`= 1-x+ 2x = 1 +x`
