In this document students use Maple to explore the relationship between activity coefficients, excess functions, and phase equilibria. start from the activity coefficient as a known property. In this study students examine how some functions change due to activities resulting in excess functions that differ from zero and vapor-liquid diagrams show complex behavior. The model avoids complex iterative procedures. In the end the vapor-liquid equilibrium equations are solved to compute both the isobaric and isothermal binary diagrams. The results are plotted and avialable for student interpretation. Additional exercises are presents for student practice.

In this document students use Maple to determine volumetric properties and compare values obtained from the ideal gas and the Soave (SRK) equations of state. Several aspects of the calculation as the effect of pressure, the lowest available volume, the number of roots, and the relation between volumen and compresibility factor are analyzed.

In this document students use Maple to explore the relationship between the extent of a reaction and the change in Gibbs free energy for that reaction. Extensions include examination of a reaction at different pressures and different temperaturescan The formation of ammonia is the chemical system used for this document..
