Finite-time fluctuation theorem for diffusion-influenced surface reactions

Abstract:

<p>A finite-time fluctuation theorem is proved for the diffusioninfluenced surface reaction A ⇌ B in a domain with any geometry where the species A and B undergo diffusive transport between the reservoir and the catalytic surface. A corresponding finite-time thermodynamic force or affnity is associated with the symmetry of the fluctuation theorem. The time dependence of the affnity and the reaction rates characterizing the stochastic process can be expressed analytically in terms of the solution of deterministic diffusion equations with specific boundary conditions. © 2018 IOP Publishing Ltd.</p>
