The vapour pressure, P, (measured in mm Hg) of liquid arsenic, is given by and that of solid arsenic by logP = -^γ^+6.69, logp=-L^L +10.8. T Calculate the temperature at which the two forms of arsenic w i l l have the same vapour pressure.

The vapour pressure of pure liquids A and B are 450 and 750 mm Hg respectively, at 350K. Find out the composition ofthe liquid mixture if total vapour pressure is 600 mm Hg. Also find the composition of the vapour phase.

Liquid mercury boils at 357°C (630 K) at 1 atm (101,325 N/m2). Calculate i t s approximate vapour pressure at 100°C (373 K), assuming that i t follows Trouton's rule.

The vapour pressure of liquid zinc as a function of temperature is given as log P (mm Hg) = - Î é l l - 1.255 log T + 12.34. Calculate the heat of vaporization of zinc at its boiling point 907°C
