520			_aThe relationship between reaction energies and activation energies has been of interest for long in the field of chemistry. Two such relationships, Brønsted–Evans– Polanyi principle and Marcus equation, are well-known and widely used. Here we derived an extended Marcus equation with reaction distance. From this equation, the parabolic curve of activation energy–reaction energy can be both upward and downward. We also predict the existence of the reverse BEP relationship in which the activation energy decreases with the increase of reaction endothermicity in a certain range.
