Thermodynamics Review 27. Given the potential energy diagram: With reference to energy, the reaction A + B → AB can best be described as 1) endothermic, having a +ΔH 2) endothermic, having a -ΔH 3) exothermic, having a +ΔH 4) exothermic, having a -ΔH 28. Apr 09, 2018 · Apr 9, 2018. Since heat is released for. C3H8(g) + 5O2(g) → 3CO2(g) +4H2O(g) + 2219.9 kJ, we say that ΔH ∘ C = − 2219.9 kJ/mol propane. We approximate that this is the change in potential energy for the reactants going to the products. The above is for an endothermic reaction. A certain feature of combustion reactions suggests that you should draw the diagram DIFFERENTLY from what you see above. The energy changes that occur during a chemical reaction can be shown in a diagram called a potential energy diagram, or sometimes called a reaction progress curve. A potential energy diagram shows the change in potential energy of a system as reactants are converted into products. The figure below shows basic potential energy diagrams for an endothermic (A) and an exothermic (B) reaction.
