The Brønsted–Evans–Polanyi relation and the volcano curve in heterogeneous catalysis
TL;DR: In this paper, it was shown that the reaction rate under given reaction conditions shows a maximum as a function of dissociative adsorption energy of the key reactant, and that for most conditions this maximum is in the same range of reaction energies.
