1.	N_(2)O_(4) harr 2NO_(2), N_(2)O_(4(g)) dissociates until the partial pressures of N_(2)O_(4) and NO_(2) become equal, initial pressure of N_(2)O_(4) is 9 atmosphere. What is K_(P) ?
Answer» 6 atm 12 atm 9 atm 8 atm Solution : partial pressure are EQUAL `IMPLIES a-X=2x` (`:. P prop n`) `implies x=(a)/(3) implies PNO_(2)=2 xx (9)/(3)=6 atm =P_(N_(2)O_(4))` `K_(P)=(P_(NO_(2))^(2))/(P_(N_(2)O_(4)))=(6^(2))/(6)=6`atm
