In fully dissociated NH_(4)CI, [NH_(4)Cl_((g)) harr NH_(3(g)) + HCl_((

1.	In fully dissociated NH_(4)CI, [NH_(4)Cl_((g)) harr NH_(3(g)) + HCl_((g))] observed vapour density is
Answer» less than the vapor density of pure `NH_(4)CI` double of the vapour density of pure `NH_(4)CI` HALF of the vapour density of pure `NH_(4)CI` ONE FOURTH of the vapour density of pure `NH_(4)CI` SOLUTION :`(D)/(d)=1+(n-1)alpha=1+alpha=2( :. alpha =1)` `d=(D)/(2) lt D`
