The discussion centers on the interpretation of the equation Δ_rH_m^⦵ = Δ_rG_m^⦵ + TΔ_rS_m^⦵ in the context of electrolytic and galvanic cells. It highlights the roles of enthalpy, Gibbs energy, and entropy in chemical reactions, emphasizing that the entropy change is primarily due to differences in the structure and aggregate states of reactants and products, rather than heat exchange. The conversation also touches on the van't Hoff equilibrium box, which is presented as a tool for understanding reversible reactions and the thermodynamics involved. Participants express confusion over the relationship between entropy changes and heat exchange, asserting that the two concepts should not be conflated. The thread concludes with a suggestion to explore the van't Hoff equilibrium box for deeper insights into these thermodynamic principles.
