Catalysts with atoms that do not have the necessary number of free valences in the ground valence state to produce a desired reaction have to be activated. The activation may be achieved by thermal energy. If the temperature is raised, part of the catalyst atoms go over into various excited valence states.
The most probable way for the activation of a metallic catalyst to go, leading directly to the formation of an active center, is to break the cohesional M-M bond.
