Plot the vapour pressure data for a mixture of benzene (B) and acetic acid (A) given
Chapter 5, Problem 5.9(choose chapter or problem)
Plot the vapour pressure data for a mixture of benzene (B) and acetic acid (A) given below and plot the vapour pressure/composition curve for the mixture at 50C. Then confirm that Raoults and Henrys laws are obeyed in the appropriate regions. Deduce the activities and activity coefficients of the components on the Raoults law basis and then, taking B as the solute, its activity and activity coefficient on a Henrys law basis. Finally, evaluate the excess Gibbs energy of the mixture over the composition range spanned by the data. xA 0.0160 0.0439 0.0835 0.1138 0.1714 pA/kPa 0.484 0.967 1.535 1.89 2.45 pB/kPa 35.05 34.29 33.28 32.64 30.90 xA 0.2973 0.3696 0.5834 0.6604 0.8437 0.9931 pA/kPa 3.31 3.83 4.84 5.36 6.76 7.29 pB/kPa 28.16 26.08 20.42 18.01 10.0 0.47
