Answer: True - An activated complex (also called a transition state) is a high-energy intermediate species that forms during a chemical reaction as reactants are converted to products. It is a fleeting species that exists for only a very short time (usually less than a picosecond) and represents the highest energy point on the reaction pathway. At this point, the reactants have absorbed enough energy to overcome the activation energy barrier, and the bonds between the atoms in the reactants are partially broken and partially formed to produce the activated complex. The activated complex then breaks down to form the products of the reaction.
