39 reaction energy diagram
This graph shows the chemical potential energy in a reaction system over time. The y-axis is potential energy in kilojoules. The x-axis is the reaction progress, or time. The far left part of the curve is horizontal and has an energy value of 50 kJ. The curve then rises to a peak of 250 kJ before falling to a horizontal region at 200 kJ. The peaks in energy diagrams for both endothermic and exothermic reaction energy diagrams are known as the transition state or the activation complex. 13 Feb 2019 — Reaction energy diagrams efficiently and effectively communicate the thermodynamics and kinetics of chemical reactions in a single diagram.
