Plot the vapour pressure data for a mixture of benzene (B) and acetic acid (A) given below
Question:
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 50°e. 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.
