1.	At equilibrium of the reaction,N_(2)O_(4) (g) hArr2 NO_(2) (g), the obsserved molecular weight ofN_(2)O_(4) is 80 g " mol "^(-1)at 350 K. The percentage of dissociation of N_(2)O_(4) (g) at 350 K is
Answer» 0.1 0.15 0.2 0.18 Solution :For the GIVEN dissociation REACTION , `alpha =(D-d)/d = (M_(t)-M_(o))/(M_(o))=(92 xx80)/80 xx 100 = 15%`
