The vapour density of `N_(2)O_(4)` at a certain temperature is `30`. Calculate the percentage dissociation of `N_(2)O_(4)` this temperature.

The vapour density of N_(2) O_(4) at certain temperature is 30 . What is the percentage dissociation of N_(2) O_(4) at that temperature ? [Hint : alpha = (D - d) // d ( n - 1) ]

The K_(p) for the reaction N_(2)O_(4)hArr2NO_(2) is 640 mm at 775 K . Calculate the percentage dissociation of N_(2)O_(4) at equilibrium pressure of 160 mm . At what pressure, the dissociation will be 50% ?
