A dilute solution of bromine in carbon tetrachloride behaves as an ideal-dilute solution. At 298 K, the vapor pressure of pure CCl4 and pure bromine are 143 Torr and 228 Torr, respectively. The Henry’s law constant for Br2 in CCl4 is 122.4 Torr. When an amount of bromine is dissolved in CCl4, the vapor pressure of CCl4 decreases by 10 Torr, comparing to pure CCl4. What will be the decrease in the vapor pressure of bromine? Calculate the composition of the vapor phase.
