Resumen:
The rigorous statistical thermodynamics of interacting linear adsorbates (k-mers) on a discrete onedimensional
space is presented in the lattice gas approximation. The coverage and temperature dependence
of the Helmholtz free energy, chemical potential, entropy, and specific heat are given. The chemical diffusion
coefficient of the adlayer is calculated through collective relaxation of density fluctuations. Transport
properties are discussed and related to features of the configurational entropy. The correspondence of the
present model to adsorption in one-dimensional nanopores is addressed.k-mers) on a discrete onedimensional
