Resumen de From Bunsen Burners to Fuel Cells: Invoking Energy Transducers To Exemplify “Paths” and Unify the Energy-Related Concepts of Thermochemistry and Thermodynamics
The conversion of chemical energy entirely into thermal energy by Bunsen burners and into thermal energy and electrical energy by fuel cells of varying efficiencies illustrates different paths by which a chemical reaction can occur. Using the efficiency of producing electrical energy as a path label allows all of the energy-related quantities to be plotted as straight lines on one graph. This readily constructed graph provides a convenient summary of these important thermochemical and thermodynamic quantities and clearly distinguishes the path independent quantities from those that are path dependent.
