40 energy diagram transition state
The peak of this energy diagram represents the transition state: an intermediate stage in the reaction from which the reaction can go in either direction. Reactions with a high activation energy will proceed very slowly, because only a few molecules will obtain enough energy to reach the transition state – even if they are highly exergonic. The entire energy diagram for the ABC system is shown in 3-D in Figure PRS.3B-3. To obtain Figure PRS.3B-2 from Figure PRS.3B-3 we start from the initial state (A + BC) and move through the valley up over the barrier, E b, (which is also in a valley) over to the valley on the other side of the barrier to the final state (A + BC).
