5B.9(a) A dilute solution of bromine in carbon tetrachloride behaves as an ideal dilute solution. The vapour pressure of pure CCl, is 33.85 Torr at 298 K. The Henry's law constant when the concentration of Br, is expressed as a mole fraction is 122.36 Torr. Calculate the vapour pressure of each component, the total pressure, and the composition of the vapour phase when the mole fraction of Br, is 0.050, on the assumption that the conditions of the ideal dilute solution are satisfied at this concentration.
