Capstone: Full Thermodynamic Profile of a Reaction

State

This capstone carries one reaction through its full thermodynamic profile — ΔS°rxn from standard molar entropies, ΔG°rxn from both available routes, the crossover temperature, and the equilibrium constant — showing all four numbers come from the same ΔH°/ΔS° pair rather than four independent calculations.

Watch for

Computing K from a ΔG° found at one temperature and then applying that same K at a different temperature ignores that both ΔG° and K are temperature-dependent quantities tied to the specific T used in the calculation.
