Spontaneous Chemical Reactions 5 - Science Project and Research Application

The Windows application, Spontaneous Chemical Reactions 5, is a great application to help students do an exceptional science project, and also to perform scientific research. It was designed for advanced students in physics and chemistry, who possess basic knowledge of calculus. The following is the chemical reaction studied:

Sulfur Dioxide (g) + Oxygen (g) -------> Sulfur Trioxide (g)

The chemical equation shows the formation of sulfur trioxide by the reaction of the gases sulfur dioxide and oxygen. Both sulfur dioxide and sulfur trioxide react with water in the atmosphere to produce sulfuric acid, one of the main components in acid rain. Therefore, it is not only valuable knowledge, but also quite interesting, to investigate under what conditions the chemical reaction of sulfur dioxide and oxygen to make sulfur trioxide is spontaneous, and at what range of temperatures is nonspontaneous. To those interested in learning how fast is the reaction taking place, that is a follow up project to do later.

For any temperature that is entered, the application calculates the entropy change in the universe, the Gibbs’ Free Energy, and the enthalpy change for the reaction. With these values, we can determine right away if the chemical reaction at the indicated temperature is spontaneous or nonspontaneous, and if it is exothermic or endothermic.

The great thing about this product is that it will save dozens of hours of hard work doing calculations. In addition, information is provided about how to present graphically the data collected.

This product includes a remarkable 15-page tutorial that explain in detail every single calculation that needs to be done for one temperature, including the two calculus integrations that have to be performed.

Again, this application is for computers using Windows 10 or newer.
