Transition-State Model Activation Energy Diagrams... 

The activation energy diagram for the reaction between O3 and O. Notice the break in the vertical scale the overall reaction is exothermic by -392 kJ. ... 

Notice that both steps of the chlorine-catalyzed reaction appear on the activation energy diagram. Each step of a mechanism has its own activation energy, so the diagram has two activation barriers. Experimental data indicate that the first barrier is higher than the second. Because the uncatalyzed reaction involves just one step, it has only...

A schematic activation energy diagram for a reaction is shown in Fig. 5. The dotted line represents the equilibrium state and the solid line a polarized state due to an applied potential. In the equilibrium state... 

Figure 5. Activation energy diagrams for metal dissolution reaction. Equilibrium state (----------) shift attributable to application of potential E (--).

Draw a hypothetical activation energy diagram for an uncatalyzed reaction. On the same set of coordinates, draw a similar graph for the catalyzed reaction. Why does reaction rate increase with the use of the catalyst ...
