The vapour pressure of mercury is 0.002 mm Hg at `27^(@)C` .`K_(c)` for the process `Hg(l)hArrHg(g) `is :

Naphthalene, a white solid used to make mothballs, has a vapour pressure of 0.10 mm Hg at 27^(@)C . Hence K_(p) and K_(c) for the equilibruim are : C_(10)Hg(s)hArr C_(10)Hg(g)

Vapour pressure of pure 'A' is 70 mm of Hg at 25^(@)C . It forms an ideal solution with 'B' in which mole fraction of A is 0.8 . If the vapour pressure of the solution is 84 mm of Hg at 25^(@)C , the vapour pressure of pure 'B' at 25^(@)C is :
