Question

The table below gives the enthalpy of benzene (1)-heptane (2) solutions at 20 °C 1 bar as a function of the mol fraction of benzene.

a) Calculate and plot the excess enthalpy at 20 °C, 1 bar.

b) Calculate the partial molar excess enthalpy at x1 = 0.2, 20 °C, 1 bar.

c)Calculate the partial molar enthalpy at x1 = 0.2, 20 °C, 1 bar

d)Calculate the heat that is released or absorbed when 10 mol of benzene is mixed with 40 mol of heptane isothermally at 20 °C, 1 bar
