Use data from Examples 9.2 and 9.3 for the thermodynamic properties of benzene (component 1) and 1-

propanol at 308.15 K (component 2). You are asked to:

1. Find the pure benzene and 1-propanol molar enthalpies at 308.15 K

2. Model the molar enthalpy of the mixture at 308.15 K with a polynomial of degree 6.

3. Find and plot the molar enthalpy of the mixture as a function of composition at 308.15 K./n4. Find and plot the partial molar enthalpies as a function of composition of benzene and 1-propanol

mixture at each 308.15 K

T = 308.15 K
