Using tabulated experimental data from the literature for either the excess molar volume or excess molar enthalpy of a system of your choice, provide the following information. 

A. A plot of the excess property (either molar volume or molar enthalpy) as a function of composition. 

B. A functional description of the excess property using the composition as an independent variable. 

C. A plot of the partial molar property (either vol ume or enthalpy) as a function of composition. 

D. Does the system behave according to the ideal solution model? If not, please explain why.

For the next three problems, use Figure P9-22 for the sulfuric acid 1 water system (Smith et al., 2005).
