A reply to the question of whether the internal energy of solid interfaces can be of a non-homogeneous nature
Arguments are provided in support of the statement that the surface excess US of the internal energy of a (solid electrode) \ liquid interphase cannot be regarded as a homogeneous function of the first degree with respect to all extensive variables, including the surface area A and the mole numbers of all components adsorbed at the interphase, when the interphase is subject to an elastic deformation.
