Program Usage Requirements: Windows Operating System Features Thermodynamic properties of 300+ compounds are provided. Saturation pressure calculator is provided for any species in the database. Solver for the Peng-Robinson and Lee-Kesler equations of state is provided. Fugacity coefficients can be solved for pure species or mixtures. Models for Gibbs energy can be fit to isobaric or isothermal vapor-liquid equilibrium data. Sample data sets are provided. The results can be plotted. Bubble-point and dew-point calculations are provided. Equilibrium constant (Kr) solver is provided. General chemical reaction equilibria calculations are provided. Equations used in the calculation process can be viewed. Installation is a one-time process. Simply download the software from http://www.wiley .com/college/koretsky. If the setup process does not start automatically, double-click Setup .exe. Once the setup process has started, follow the on-screen instructions. This process needs to be completed only for the first-time installation. Once the software has been installed, you may consult the Documentation program for more detailed documentation, including screenshots and descriptions of the numerical methods used to solve these problems. Click Start, Programs, ThermoSolver, and click the ThermoSolver program icon to begin. The Thermodynamics Menu will appear. From here, eight programs are available to choose from: Species Database The thermodynamic properties of more than 300 species are available from here. Choose a species from the drop-down list at the top of the screen; the list is sorted by reduced chemical formula, so "Ethanol" will be found under "C2H60." Use the scrollbar at the side of the drop-down list to choose a species quickly.
