Interrelationship of differential changes of thermodynamic potentials in a system in which a reaction takes place intending to obtain useful work in isentropic conditions–lectures adapted to sensing learners
Year: 2025
Type: article
Abstract: The educational content of physical chemistry can be a burden for students who are classified as sensing learners (SL). Therefore, for SL, the lecturer must adapt the educational material reflected in standardizing certain procedures (for example, performing and proving similar expressions–differential changes of thermodynamic potentials) and visualization of abstract concepts and expressions. Here is presented the connection of differential changes of thermodynamic potentials in isentropic conditions with useful work (in the system, there is one exothermic reaction in the quasi-static regime) and with the differential change of internal energy in an adiabatic and isochoric composite system (reactive system + corresponding reservoir) as well as with the differential change of internal energy in the isochoric composite system. When defining an isentropic process (or system), the change in entropy that is a consequence of heat exchange and the change in entropy that is a consequence of a chemical reaction is considered. Differential changes in thermodynamic potentials are also shown schematically, facilitating SL’s mastery of the material.
