15.2 Plot the vapour pressure data for a mixture of benzene (B) and ethanoic acid (E) given below and plot the vapour pressure/composition curve for the mixture at 50 \deg C. Then confirm that Raoult's and Henry's laws are obeyed in the appropriate regions. Deduce the activities and activity coefficients of the components on the Raoult's law basis and then, taking B as the solute, its activity and activity coefficient on a Henry's law basis. Finally, evaluate the excess Gibbs energy of the mixture over the composition range spanned by the data. 0.0160 0.0439 XE 0.0835 0.1138 0.1714 0.484 0.967 1.535 1.89 2.45 Pi/kPa Pg/ kPa 35.05 34.29 33.28 32.64 30.90 0.3696 0.5834 0.2973 0.6604 0.8437 0.9931 X
