Gibbs Energy vs. Temperature Graph Construction Tool
With this web page you can create graphs of G vs. T from actual National Institute of Standards and Technology data. ALL DATA ARE GAS-PHASE DATA. You can select a chemical equation that is already on the list, or you can create your own. If you create your own and you use a species that is not already in the database, the web page will interact with the server and get the necessary data from the NIST Chemistry Webbook automatically. A vertical distance between curves on this graph is DELTA_r_G, also known as the REACTION POTENTIAL. Excel-ready data will appear here.
Partial Pressures (bar):
Once an equation is selected, you can specify the partial pressures of the gases. This will change the molar entropies and affect the curve slopes.
